overview | n-butyl glycidyl ether is a colorless liquid with a slightly irritating smell. it is used as a viscosity reducer and chemical intermediate for epoxy resin and as a solvent stabilizer for chlorination. |
Preparation | n-butyl glycidyl ether was synthesized with n-butanol and epichlorohydrin as raw materials, boron trifluoride ether complex as catalyst, and sodium hydroxide as the closed loop agent for the cyclic reaction. |
use | epoxy resin reactive diluent has toughening effect, and can also be used as stabilizer and plasticizer of polyvinyl chloride this product can be used as reactive diluent of bisphenol a epoxy resin. Small toxicity, easy to use. And can improve the properties of some resins after hardening, such as impact strength. used as a reactive diluent mainly used for the synthesis of isobutyric acid ester products, with more than 100 varieties. The main ester products are methyl isobutyrate, propyl ester, isoamyl |
Production method | From butanol and epichlorohydrin as raw materials, it is synthesized through a two-step reaction. The specific technological process is as follows: 267kg of butanol and 32kg of concentrated sulfuric acid with a concentration of 96% are added to the reaction kettle, stirred, raised to 55 ℃, 324kg of epichlorohydrin is added dropwise, the temperature is controlled at 55-60 ℃ for about 4 hours, and the temperature is kept at 60-65 ℃ for 2 hours. Then, cool to 45 ℃, slowly add the mixed solution of tin tetrachloride and butanol (5kg tin tetrachloride dissolved in 5kg butanol), and then keep the temperature at 60-65 ℃ for 4 hours. After the reaction, decompressed distillation recovers unreacted epichlorohydrin and butanol until the temperature reaches 85-95 ℃ and the vacuum degree is 93.1kPa without epichlorohydrin and butanol. The epichlorohydrin butyl ether was obtained. The above reaction materials are cooled to 30-35 ℃, 432kg of sodium hydroxide with a concentration of 30% is added dropwise for about 4 hours, then the temperature is raised to 35-40 ℃ and the temperature is kept for 3 hours, then pure benzene is added under stirring, the temperature is raised until brine and alkaline water are released, and then the pH is about 6.5-7. Release the washing water, raise the temperature and remove benzene at normal pressure until the temperature of the feed liquid reaches 140 ℃, and then cool the discharge. The total yield of the two steps is about 95% based on butanol. |
