Unconventional reactivity of epichlorohydrin in the presence of triphenylphosphine: isolation of ((1,4-dioxane-2,5-diyl)-bis-(methylene))-bis-(triphenylphosphonium) chloride

The selective formation of the heterocyclic salt ((1,4-dioxane-2,5-diyl)-bis-(methylene))-bis-(triphenylphosphonium) chloride was observed when epichlorohydrin and triphenylphosphine were reacted in CH2Cl2 at room temperature. Slow evaporation from a mixture of ethanol and ethyl acetate allows to isolate monocrystals of the heterocyclic phosphonium salt. Mechanistic investigations point to the formation of the zwitterionic intermediate 1-chloro-3-(triphenylphosphonio)-propan-2-olate, which can dimerize and generate the 1,4-dioxane derivative. In the exclusive presence of a Br?nsted acid as HCl, which usually facilitates epoxide ring opening, the exclusive formation of 1,3-dichloro-2-propanol was although observed. Also, when epichlorohydrin, PPh3, and a stoichiometric amount of HCl were mixed, (2-chloro-3-hydroxypropyl)-triphenylphosphonium chloride was formed and its isolation in pure form provides monocrystals subjectable to X-ray analysis.

Preparation method of sodium beta-glycerophosphate containing crystal water

The invention discloses a preparation method of sodium beta-glycerophosphate containing crystal water. The method comprises the following steps: A) taking epoxy chloropropane as an initial raw material, slowly dropwise adding the epoxy chloropropane into hydrochloric acid, reacting for 1-6 hours, adjusting the pH value to 3-4 by using a sodium hydroxide solution, carrying out vacuum distillation to remove moisture, distilling to 60 DEG C, adding a drying agent, stirring for 1 hour, and filtering to obtain 1, 3-dichloropropanol; B) adding the 1,3-dichloropropanol into an esterification reactionkettle, adding a phosphating agent, heating the temperature to 80-130 DEG C, controlling the temperature to esterify for 10-20 hours, after esterification is finished, adding water for dilution, dropwise adding the sodium hydroxide solution, adjusting the pH value to be 9-13, keeping the temperature at 40-80 DEG C, hydrolyzing for 3-5 hours, adding magnesium oxide or calcium oxide and stirring for 2 hours at 60-80 DEG C, adding activated carbon and stirring for 1 hour, the negative pressure distillation concentration being 70%-75%, adding ethyl alcohol, carrying out cooling and stirring and filtering to obtain the sodium beta-glycerophosphate. According to the invention, the generation of sodium alpha-glycerophosphate is avoided, and the sodium beta-glycerophosphate containing crystal water and not containing crystal water can be flexibly prepared.
