Brief manufacture process:
The butanol and epichlorohydrin were synthesized by two steps reaction. The specific process is: 267kg butanol and 32kg concentrated sulfuric acid concentration of 96% into the reactor, stirring, heating to 55 ° C, dropping epichlorohydrin 324kg, temperature control in 55-60 ° C about 4h plus finished, and then in the 60-65 ℃ heat preservation 2h. Then, the mixture was cooled to 45 ° C and a mixture of tin tetrachloride and butanol was slowly added (5 kg of tin tetrachloride was dissolved in 5 kg of butanol), and the reaction was further incubated at 60-65 ° C for 4 h. After the reaction, The unreacted epichlorohydrin and butanol were distilled off until the temperature reached 85-95 ° C and the degree of vacuum was 93.1 kPa without epichlorohydrin and butanol distilled off. To give epichlorohydrin butyl ether. The reaction of the material cooled to 30-35 ° C, dropping concentration of 30% sodium hydroxide 432kg, about 4h plus finished, and then heated to 35-40 ° C and heat reaction 3h, then add pure benzene under stirring, warming to put The brine and alkaline water are removed and then washed with water to a pH of about 6.5-7. Let wash water, temperature and pressure benzene, until the liquid temperature reached 140 ℃, and then cooling the discharge. The overall yield in two steps was about 95% based on butanol.
