HC WIRE: Plasticizer Plastic processing additives production and consumption of the largest varieties, which yield about Plastic Additives 60%, mainly used for soft PVC products, consumption of about 85% of its total, are also used such as poly vinyl acetate resin, polyvinylidene chloride, Polyethylene Alcohol, cellulose and its derivatives, polyamide, etc.. The role of plasticizer to polymer softening, increase flexibility, and lower melt temperature, ease of molding a promoter, it is generally a less volatile liquid organic compounds of high boiling point, a few are low melting point solid. Plasticizer according to the chemical structure can be divided into: phthalate esters, isophthalic acid esters, acid esters, adipic esters, sebacic esters, phosphate, stearic acid ester, lauric acid esters, citric acid esters, oleic acid esters, trimellitic esters, ethylene derivatives, acid derivatives, maleic esters, fumaric acid esters, clothing Hong esters, polyol derivatives, chlorinated plasticizers, polymeric plasticizers, etc. [8].

2007 capacity of 2.5 million years, t / a, output was 1.15 million tons, consumption reached 1.5 million tons, imported 410,000 tons, export only 23,000 tons. Imports were higher than the same period in 2006 decreased 4.6% DOP270760.7 tons, compared with same period in 2006 decreased 0.3%; DBP import 110.179 tons compared to same period in 2006 decreased 88.9%; DINP and DIDP import 94,623.56 tons, an increase of 24.7% over last year . Thus, in addition to DINP, DIDP, the plasticizer production, marketing and consumption of overall decline in [9,10].

Current consumption structure of China's roughly plasticizer market: leather goods accounted for 17.5%, 9% of foam products, film products accounted for 35%, 18% footwear, wire and cable, 7.5% Other Products accounted for 13%.

20 t / a unit with three companies of more than 10 million? 200 000 t / a unit of enterprises 4 ,5 - 100 000 t / a unit of the company has six, 1 - 5 t / a unit, there are 10 home, the next few years, small-scale, equipment, technology will be backward conversion or closure of enterprises, production is more concentrated, but the growth rate will gradually become smaller, it is estimated By 2010, with the PVC Over-supply of resin, plasticizer consumption will decline, the maximum capacity of about 2.6 million tons / year. 2008 production capacity and consumption growth started to decrease production Zeyi 5% - 10% growth rate. RoHS, WEEE dual instruction under the influence of plasticizer industry has begun to change the product structure, environment-friendly production of plasticizer epoxidized soybean oil from 4 million tonnes in 2003 to 2007, 240,000 tons / year , DINP from 5 tons to 140,000 tons / year, citric acid esters and trimellitic ester production also increased significantly. We should focus on the development of citric acid esters, vegetable oil-based, polymer-based, cyclohexane diester series of plasticizers and other non-toxic environmentally friendly ionic liquid plasticizer.

2.2 and the industry is faced with a problem
(1) 2007 International crude oil prices off stiff like the Mustang, or up to 50%, driving up the prices of downstream chemicals, plasticizers squeeze the profit margins of downstream products, especially raw materials, small, octanol prices higher than the DOP prices, the industry struggled.

(2) the EU introduced restrictions on adjacent benzene plasticizers in packaging, medical, toys and other products in the use and implementation of environmental bills, resulting in China Plastic Products Export restricted, a significant reduction in exports, affecting the market such as o-benzene plasticizer DOP demand.

(3) introduction of lower export tax rebate policy in China and national implementation of the macro-control policies, serious blow to the production of downstream processing initiative.

(4) counterfeit products flooding the market, not only occupied the plasticizer market consumption, and greatly disturbed the market order.

(5) plasticizer imports and sales of foreign-funded enterprises in China, a significant increase, about half of total domestic consumption, a serious impact on the domestic market.

(6) the state has adopted energy conservation policies, increase the environmental management efforts, coupled with rising energy prices, tight capacity, and national production of hazardous chemicals, transport and rectification, all of the industry had some fixed negative impact.

(7) lack of communication within the industry and Cooperation , Buy materials, to suppress prices, disorderly competition serious.

Reduce the causes of market demand, a lot of idle capacity, low efficiency of the sector. Restricted two plasticizer industry, while raw material supply, while the other product sales difficulties, industry manufacturers to open to open the stop, the industry began less than 50%, to substantially increase the cost can be said that 2007 was a plasticized agents feel the pressure the industry's biggest year [10].

From the macro view of the situation and market situation, the situation is bleaker in 2008, the national macro-control policies will be further augmented, plasticizer industry will face greater challenges, the long-term plasticizer market downturn, but also anhydride will drag the market.

2.3 key industry issues 2.3.1 Esterification Catalysts speed up the pace of R & D

REACH regulations will also test the quality of plasticizer, due to the backward synthesis of plasticizers, heavy metals were higher, too difficult to pass these directives, regulations, and therefore exports will be affected. Should accelerate the development of catalytic efficiency, low emissions, waste water treatment process easier, to further improve the plasticizer product quality, improve industrial production environment and reduce production costs. To this end, in the future to adopt a new esterification catalysts, such as solid super acid, rare earth solid catalyst, solid heteropoly acid curing catalyst system or other solid acid catalysts.

2.3.2 gradual adjustment of product structure, strengthen the new products, and promote
