So far, domestic and foreign industrial production methods they use a liquid TDI light gasification process. When Bayer in 2010 in Shanghai, 30 million t / aTDI plant put into operation, this will be the first application the company developed a gas-phase production of TDI's new craft world-class device. China's China National Bluestar, Yantai Juli, Gansu and other companies are using silver liquid light gasification technology. Phosgene reaction process generally consists of 5 elements: carbon monoxide, phosgene and chlorine reaction; reaction of toluene with nitric acid dinitrotoluene (DNT); DNT react with hydrogen toluene diamine (TDA); treated dry TDA reaction with phosgene toluene diisocyanate (TDI); TDI purification. 1.2 Non-optical gasification present instead of phosgene manufacture of isocyanate process,

there are three, namely: (1) primary amines and carbon dioxide or dimethyl carbonate manufacturing isocyanate; (2) the primary amine and carbon monoxide oxidation carbonylation of manufacturing isocyanates, nitric benzene; (3) reduction of carbonyl carbon monoxide, isocyanate manufacturing. More hopeful and promising is the primary amines and dimethyl carbonate formation in the catalyst under the action of urethane, urethane and then the decomposition of TDI, the methanol can be reused by-products produced dimethyl carbonate, dimethyl carbonate as the basis of a non-toxic chemical pollution, which replaces the light gas, environmental protection, safety benefit, because of its roots during the reaction does not contain chlorine, corrosion, material requirements of the equipment is low, so it is a Green, clean production process. But the high cost of these three processes, low yield, is in the research and development process, can not be industrialized. 2. Production Status 2.1 TDI production and demand situation in the global TDI 2.1.1 Global production the world more than 30 companies,baby hat
more than 40 sets of equipment in the production of TDI, the total production capacity of 200 million t / a or so. The major foreign manufacturers are: DOWChemical (production capacity 160,000 t), BayerAG, BASFAG, Mitsui Takeda Chemical Co., Ltd. (production capacity of 240,000 t / a), Japan Polyurethane Industries, Korea KFC Corporation (production capacity 100,000 t / a ) and the OCI Corporation (capacity 50,000 t / a), China Taiwan South Asia, Chemistry (capacity 30,000 t / a), Poland. 2.1.2 global supply and demand situation TDI global supply point of view, because the downstream demand for TDI in Europe and America a slight slowdown, coupled with environmental constraints, leading to Europe, the Americas TDI production declining in recent years. Consumption is rising every year and double production capacity continued to decrease in pressure, making the TDI suppliers and downstream industry had to change its marketing strategy, production and sales gradually shift to the Asian region. Therefore, promotional gifts
TDI's new capacity in recent years have focused on Asia, the Asian region and market share of supply also will increase every year. And Asia in recent years the global production and demand shown in Table 2. As can be seen from the table after 2005 changes in the global supply and demand larger TDI, mainly from Europe and the transfer of production capacity and some large installations due to maintenance shutdown. Asia has shown a steady growth trend demand, production capacity also will be rapid growth, but relatively fast growth in 2005, TDI supply and demand balance. The formation of this trend for two reasons, first in Europe and America to Asia, the transfer of production capacity, and second, several Chinese manufacturers in particular Cangzhou Dahua TDI and Gansu silver will continue to improve the existing process, TDI technology has made great progress made to improve capacity utilization. 2.2 Domestic production and supply and demand 2.2.1 TDI TDI domestic production in 2007, TDI production capacity of 290,000 t / a, corporate gifts

In addition, Yantai Juli has annual production capacity of 30,000 tTDI. TDI manufacturing process from the international technical point of view, the main process is divided into two routes: one to Sweden, the United States, the traditional process-based DuPont technology; Second, newsboy cap
BASF of Germany, represented by improved process technology. Looking at the situation from domestic manufacturers, Gansu silver company BASF using the technology, and China National Bluestar Cangzhou Dahua DuPont technology is used. By comparing the two processes, we can see in the hydrogenation of TDI technology (TDA synthesis) of the core technology: BASF process uses high-speed turbine agitator vacuum mixing hydrogen technology, the reaction using ethanol as solvent, catalytic hydrogenation with nickel catalyst. The advantage is uniform reaction, catalyst separation process is simple, low loss catalyst, the reactor agitator drawback is easy to damage the mechanical seal, material quality requirements. The DuPont process using high-power high flow reverse circulation pump spray hydrogen technology, the use of palladium carbon hydrogenation catalyst, the reaction does not use the advantage of solvent, the disadvantage is the high energy consumption, bucket hat
complicated separation process catalyst, catalyst big loss. Manufacturing process in the photochemical reaction of TDI (TDI synthesis) of the core technology: BASF process using high boiling point DEIP (diethyl phthalate) solvents, spray tower two reaction process, the advantage of mixing, the reaction completely , less by-products, high purity; disadvantage is the high boiling point solvent in the reaction DEIP phosgene process will occur with the side effects, consumption of large and by-products produced by reaction with the solvent return system, making it easy response system congestion. The DuPont technology is used in ODCB (o-dichlorobenzene) one-step production process light solvent, the relative advantages of process simplification, solvent consumption is low, side effects do not occur, the disadvantage is the one-step reaction of low yield, higher raw material consumption likely to cause TDI costs. TDI product quality requirements of the major high-purity (99.5%, Shanghai BASF product purity as high as 99.86%, 2,4 TDI ≥ 80 ± 1,2,6 TDI ≥ 20 ± 1) low hydrolyzable chlorine content (≤ 0.01%, Shanghai BASF products reached 0.005%), fedora hats
