Problems solved by technology

[0002] Ethylene glycol is an important organic chemical raw material, mainly used to produce alkyd resin, polyester, antifreeze, non-ionic surfactant, ethanolamine and explosives, etc. The demand for it in my country is very large. On the one hand, it is used to prepare ethylene glycol The disadvantages of alcohol are very obvious. It relies on petroleum resources, consumes a lot of water, and costs high. On the other hand, the amount of ethylene glycol used is very large, resulting in a large number of ethylene glycol waste. The treatment of ethylene glycol waste has always been a major problem for people. The application of ethylene glycol as a synthetic material in the production of alkyd resins has a great impact on the water resistance and acid and alkali resistance of alkyd resins. How to apply ethylene glycol waste in the synthesis process of alkyd resins for Effective recycling of diol waste can not only purify the environment and reduce pollution, but also turn waste into treasure and save a lot of petroleum resources
