Description
Technical field
The invention belongs to technical field of organic synthesis, and in particular to the synthetic method of one kind 1,3- propene sultones.
Background technology
Because use is little before 1,3- propene sultone, rarely has the report of its synthetic method.In recent years, due to it
Available for lithium battery additive, therefore it is taken seriously, the patent of invention around its synthetic method increases rapidly, is summed up, main
There are following several routes:
1st, using propylene as Material synthesis 1,3- propene sultones, see:CN105622833;
2nd, using enoyl- chlorine or bromine as Material synthesis 1,3- propene sultones, see:JP2009108934、
WO2006085149, JP2009076617 and WO206088149;
3rd, with 1,3-PS for Material synthesis 1,3- propene sultones, see Kr2007101716, CN106279097,
JP2009076617, Kr2009076617 and WO2006085149;
4th, using chlorination glycerine as Material synthesis 1,3- propene sultones, WO2011016440 is seen;

Liquid B;
3rd, in reaction bulb, water and remaining sodium sulfite, stirring and dissolving are added, continuously adds remaining t-butyl peroxy
Change hydrogen, after stirring and dissolving, dropping liquid A and dropping liquid B is added dropwise simultaneously into reaction bulb, time for adding 4~5 hours, process is added dropwise
The pH of beginning control system is 7.5~8.
Further, in step 2.4, added into flash distillation bottle to mequinol as polymerization inhibitor, mequinol is added
Quality is the 0.01~0.1 of 3- hydroxy sulfonic acid quality.
Further, in step 2.3.2, be concentrated under reduced pressure into material it is sticky before, be first evacuated to 0.09MPa, and depressurize dense
All the time 90~100 DEG C of kettle degree is controlled in compression process.
Further, in step 2.3.2, by filtrate air-distillation to kettle temperature up to 90~100 DEG C, then it is evacuated to 0.01~
0.1MPa, kettle temperature is concentrated under reduced pressure into up to 125~135 DEG C, untill being concentrated into not water outlet.
Further, it is by the method that 1,3- propene sultones further purify:The 1,3- propylene sulphurs that step 2.4 is obtained
Acid lactone dichloromethane or ethyl acetate dissolving, filtering, filtering are recrystallized with n-hexane, filtered, dried, obtain more high-purity
The 1,3- propene sultones of degree.
