Rubber chemicals on a rapid increase in demand for aniline

1 Overview

China's rubber chemicals aniline one of the main areas of consumption, most of the accelerator and antioxidant are the production of aniline as a starting material, the rubber chemicals industry aniline become the most basic and most important raw materials. Since 2004, domestic prices rose aniline, from the beginning of 7500 yuan per ton has risen to mid-November of 15,000 yuan per ton, leading to many varieties of rubber chemicals production and profit margins dropped. Therefore, domestic enterprises, including rubber chemicals businesses plan to expand the production capacity of aniline to meet the demand for rubber chemicals industry. As China's automobile, the rapid development of rubber industry, and to stimulate the pull of China's rubber chemicals industry in the next few years will be the development of the rubber chemicals Aniline demand for a fast-growing momentum, the following analysis will focus on the rubber chemicals aniline The demand for rubber chemicals producers and the planned production of aniline reference.

2 demand

In recent years, China's car with the rubber chemicals and rubber industry development, production and demand for a rapid increase in year on year, according to the China Rubber Industry Association of Professional Committee of rubber chemicals and Statistics, in 2003 China's total output of rubber chemicals for the 206,000 t, One promoter 83,500 t, antioxidant 62,500 t, processing aids about 40,000 t, and other functional additives 20,000 t.

Among them, aniline was synthesized from the rubber chemicals and intermediates are: promoter M (all times are Sulfonamide promoter promoter M for Mother ring, such as accelerator DM, CBS, NOBS, NS), One promoter CBS to promote the agent and M-ring has been for the production of raw materials, and the ring has been by-aniline as raw materials to produce; antioxidant A, B, RD, 3100, H, and so on in order to direct aniline as raw materials; antioxidant, such as BL E Diphenylamine type of antioxidant for the raw materials to diphenylamine, and aniline Diphenylamine again for the production of raw materials; leading antioxidant 4010NA, 4020 as a raw material for Aminodiphenylamine, while Aminodiphenylamine are raw materials for the production of aniline. One promoter M consumption per ton aniline 500kg, for Aminodiphenylamine consumption per ton aniline 670kg, antioxidant RD consumption per ton aniline 560kg, antioxidant A unit consumption per ton aniline 440kg, antioxidant D unit consumption per ton aniline 430kg.

In recent years, many domestic small and medium-sized enterprises to invest in construction of rubber chemicals unit, in particular the simple process of promoter species, so the actual production than the large number of statistical data, according to the 2003 domestic rubber chemicals in various types of production is relatively conservative projections aniline consumption Volume: M promoter consumption aniline 13,000 or so t; consumption of antioxidant RD aniline 11,000 or so t; Diphenylamine antioxidant category (mainly in BL E) aniline consumption of 04,000 t or so; old age 3100 agent and H small varieties such as aniline consumption of antioxidant amines 02,000 or so t; antioxidant A and D consumption aniline 02,000 or so t; of Aminodiphenylamine (with exports of around 10,000 t) p 2 consumption. About 40,000 t, and other rubber accelerator, antioxidant additives and processing some varieties aniline consumption of about 05,000 t or so, the rubber chemicals in 2003 in the field of aniline consumption of about 61,000 t or so (not including the promotion of CBS agent has ring-consumption equivalent to the amount of aniline, if this part of the increase, reaching about 6.7 to 68,000 t).

3 demand forecast

In view of the domestic tire industry, the rapid development of China's tire production in 2003 reached 187,850,000, of which 68,870,000 radial tire, and last year respectively year-on-year increase of 16.43 percent and 39.39 percent. According to the Rubber Association forecasts show that from 2004 to 2005, China will be the new radial tire production capacity more than 20,000,000, which requires the rapid growth of the additive. In the second half of 2004, almost all varieties of additives are presented in short supply situation, and many of the domestic rubber chemicals and intermediates are very optimistic about the prospects for exports, such as meeting domestic Sulfonamide promoter, antioxidant RD, for Aminodiphenylamine, Central Amines have been, and so on diphenylamine. Therefore, the major domestic manufacturers plan to expand their rubber chemicals and intermediates production unit, the major expansion plan is as follows.

1. Enhancers M. Sulfonamide time promoter as a leading promoter of the development of varieties in recent years, there are two more than domestic production, raw materials they need are the promoter M or DM, therefore, domestic M promoter of supply and demand tension. Thorpe Zhenjiang, additives plant in northeast (Hengshui) are intended to promote the expansion of the M agent device, and Lin Wei-Puyang in 2003 with an annual output of 5000t new promoter M production is expected in 2006 to promote domestic production capacity will reach M Agent 3 . 80,000 t more than a year aniline about 19,000 t.

2. Antioxidant RD. Since 2004, domestic demand for antioxidant RD rapid growth in market supply and become rubber chemicals in the area of one of the most tight species. Sinopec Nanjing Chemical Plant Plan in 2005 will be extended to produce devices with an annual output of 15000t, St. Shandong Chemical Co., Ltd. plans to Austria in 2005 with an annual output of 10,000 t of new antioxidant plant RD. As the bullish market, a few domestic enterprises have the intention of the new large-scale production of antioxidant RD device. In addition Compton of the United States plans to seek Chinese partners in the production of antioxidant RD. To consider building a large-scale installations put into operation, some of the less competitive small devices have been forced to close, in 2006 China is expected to rubber antioxidant RD will reach an annual production capacity of 40,000 t, will take about a year aniline 23,000 t.

3. Aminodiphenylamine to be the world's leading antioxidant 4010NA, 4020 of raw materials, with the successful development of nitrobenzene and aniline condensation of the cleaning process, and a greater demand for its neighboring countries, the annual export volume reached 10,000 t about the major manufacturers have plans over the next few years to expand production scale. Nanjing Chemical Plant with an annual production capacity of about 22,000 t; St. Shandong Chemical Co., Ltd. plans to Austria in 2005 to expand production capacity to an annual output of 40,000 t; other Tongling Xinda Chemical Co., Ltd., Jiangsu Tung Lung, Shandong fly Ningyang There are also up for the plan to expand the existing Aminodiphenylamine production capacity. Of course, many businesses at the same time supporting the expansion of downstream products such as the varieties of antioxidant 4020, is expected in 2006 on domestic Aminodiphenylamine annual production capacity of about 75,000 t, about 50,000 t about aniline and nitrobenzene are used basically Production.

4. Cyclohexylamine. Cyclohexylamine the main promoter for the production of sodium cyclamate and CBS as an ideal and in line with the national conditions of the environment-friendly agent to promote rapid growth in recent years, CBS in 2003, domestic production capacity of more than 20,000 t, production of about 17000t, 2003 in the second half so far , Domestic enterprises are under way or are planned to promote the expansion of new agents and equipment CBS. According to incomplete dollars in 2004 to add an annual production capacity will reach around 8000t, 2006, CBS is expected to produce cyclohexylamine will consume about 11,000 t equivalent to the consumption of aniline 12,000 t around.

5. Other species of small benzidine consumption increases and decreases, such as A and D, and other antioxidant naphthylamine antioxidant production will be reduced year by year, and the antioxidant 3100, 4PPD, H production will be increased year by year, the demand for the relative antioxidant Aniline Stability, diphenylamine for export, it is expected that other rubber chemicals and intermediates, and other varieties of steady growth in demand for aniline, aniline consumption in 2006 to about 1.3 to 15,000 t. To sum up, in 2006 the domestic rubber chemicals industry about the need for the number of aniline 11.7 ~ 119,000 t. 2006 is expected to be rubber chemicals at the 4, 4, 2 diphenylmethane diisocyanate (referred to as MDI) after the second-largest user.
