Use | Bis (2-chloroethyl)-(2-chloroethyl) phosphonate is referred to as phosphonate diester, which is a plant growth regulator Ethephon intermediate. |
Production method | The preparation method of bis (2-chloroethyl)-(2-chloroethyl) phosphonate is composed of tris (2-chloroethyl) phosphite The ester is rearranged to obtain phosphonate diester. Tris (2-chloroethyl) phosphite is added from the bottom of the stainless steel reactor with a stirrer, overflows from the top, and is continuously rearranged under stirring. The temperature is controlled at 220-240 ℃, the flow rate is 75-80kg/h, and the residence time is about 10min to obtain phosphonate diester with a content of more than 60%. |
