Embodiment 1
[0028] The fixed-bed reactor is filled with a 10% sodium hydroxide catalyst loaded with alumina, and the methanol with a content of 99% is first transported into the tubular fixed-bed reactor at a flow rate of 20 mL / min using a constant-flow pump 0, and then the methanol with a content of 99.5% epichlorohydrin was sent into the tubular fixed-bed reactor at a flow rate of 20mL / min using constant flow pump 1, and hydrogen sulfide with a content of 99.9% was sent into the tube at a flow rate of 24mL / min using booster pump 2. Type fixed-bed reactor, keep the reactor pressure at 0.1MPa, cool the tubular reactor to 0-10°C through a low-temperature circulation device to perform ring-opening substitution reaction to obtain compound 1; then add 10mol compound 1, 3780g methanol, 635g iodine , 50g of tetrabutylammonium bromide was added to the reactor for oxidation reaction, the temperature was kept at 25°C, and the reaction was carried out for 4h to obtain bis(3-chloro-2-hydroxypropyl)di...
