GC-YP Industrial Dimethyl phosphite for Specific Gas Chromatography
Phosphonic acid, dimethyl ester; Dimethyl phosphite;
Molecular weight: 110.05
CAS Number: 868-85-9
Nature: colorless flow of liquid. The boiling point of 170-171 ℃, 56.5 ℃ (1.07kPa), the relative density of 1.200 (24/4 ℃), refractive index of 1.4035, flash point 29 ℃. Soluble in water and most organic solvents.
Preparation: methanol and phosphorus trichloride reaction derived.
Uses: used as lubricants additives, adhesives and some organic synthesis intermediates. For the synthesis of insecticides omethoate, methyl thiophosphate and herbicide glyphosate and so on.
          Dimethyl phosphite is not only an important intermediate for the production of herbicide glyphosate, but also an important raw material for textile flame retardants and other chemical products. It is mainly used in chemical analysis, which is complicated and inefficient. In order to meet the test and production, Tengzhou City, the vast chromatographic equipment Technology Co., Ltd., advancing with the times to scientific development as a guide, under the leadership of Wang Xiaoying manager, relying on Xiangying Institute of Analytical Technology, chromatography and engineering research, analysis and testing Center 3 scientific research units, developed GC-YP industrial dimethyl phosphite determination of special gas chromatography, the use of special column determination of dimethyl phosphite content, obtained satisfactory results.
