-
Paragraph 0023; 0026-0028, (2021/09/27)
PROBLEM TO BE SOLVED: To provide a method whereby, a phosphate compound selected from the group consisting of orthophosphoric acid, phosphonic acid, phosphinic acid, and anhydrides of them is used as raw material and, by one stage reaction, a corresponding phosphoester compound is produced. SOLUTION: To an aqueous solution of a phosphate compound, added is an organic silane or siloxane compound having an alkoxy group or an aryloxy group, and the mixture is subjected to a heating reaction, thereby producing a corresponding phosphoester compound without requiring a catalyst.

-
Paragraph 0029; 0030; 0031, (2016/11/21)
The invention provides a preparation method for n-propyl phosphate. The preparation method comprises the following steps: (1) reacting tri-n-propyl phosphite with bromopropane under the catalysis of potassium iodide to obtain n-propyl di-n-propyl phosphate, wherein the reaction temperature is 50-70 DEG C; (2) reacting n-propyl di-n-propyl phosphate with trimethylsilyl chloride at the circumfluence temperature in an aprotic solvent under the catalysis of potassium bromide or potassium iodide to obtain n-propyl phosphate. The preparation method is easy to get the adopted raw materials, low in toxicity, less in by-products, easy to purify, low in cost and suitable for industrialized production. The reaction route of the preparation method is as follows: (as is shown in the Specification).

The novel eco-efficient methods to transform white phosphorus into the esters of phosphoric, phosphorous and phosphonic acids, tertiary phosphines and other organophosphorus compounds under conditions of electrochemical catalysis were elaborated. The mechanism of these processes was investigated using the method of cyclic voltammetry and preparative electrolysis.
