China 1,4-cyclohexanedimethanol (CHDM) industry research and investment decision-making report (2022 Edition)

Content introduction ：

CHDM It is a white waxy solid , It is an important organic chemical raw material , CIS 、 Trans has two structures .1,4- Cyclohexane dimethyl alcohol (CHDM) It's paint , ink , adhesive , Insulating materials and intermediates of saturated polyester and unsaturated polyester for some special purposes , The biggest use is in synthesis PCT、PETG、PCTG New polyester , The product has good transparency 、 Impact resistance 、 Wear resistance and corrosion resistance .

Japanese Application CHDM Produce resin coating , High performance diaphragm , The annual demand for high-end liquid crystal materials is growing , meanwhile , The demand of other European countries is also growing .

CHDM It is mainly composed of dimethyl terephthalate (DMT) Prepared by two-step hydrogenation reaction , from DMT The benzene ring is saturated and hydrogenated to form 1,4- Dimethyl cyclohexanedicarboxylate (DMCD), Then through the ester group hydrogenolysis, the intermediate product 4-( Methoxycarbonyl ) Cyclohexane methanol (CMCHM) The last generation CHDM.

CHDM by DMT After two different hydrogenation reactions , At present, the production devices that have been built in China are DMT Purchased or imported , Before the market price , production 1 Tons of CHDM, The required DMT The cost of raw materials accounts for 1.4 Ten thousand yuan .

The domestic CHDM The production scale of the production device is small , The cost of production is high , Market application is restricted , The production load of the device is low , It forms a vicious circle .

At home CHMD Mainly from South Korea 、 Imported from the United States . Foreign products （ content 99%） The import retail price is 1500-1700 element /kg.

Only Kailing Chemical Co., Ltd. is the production enterprise that normally starts production in China （ Zhangjiagang ） Limited company , Its annual capacity 2 Ten thousand tons of / year .
