Trimethyl phosphite Specification

The Trimethyl phosphite, with its CAS registry number 121-45-9, is a kind of clear colorless liquid with a strong foul odor. This chemical is sensitive to air and moisture. It can also be named as fosforyntrojmetylowy;Methyl phosphite ((MeO)3P); P(OCH3)3; Phosphonousacidtrimethylester; Trimethoxyfosfin. As to its usage, it is widely applied in many ways. It could be used as the organic phosphorus pesticide intermediates, such as for the dichlorvos, phosphorous amines and monocrotophos; And it could also be used as flame retardants of plastic and wood, as well as catalyst of synthetic polymer and additive of painting.

Physical properties about Trimethyl phosphite are: (1)ACD/LogP: -0.797; (2)ACD/LogD (pH 5.5): -0.80; (3)ACD/LogD (pH 7.4): -0.80; (4)ACD/BCF (pH 5.5): 1.00; (5)ACD/BCF (pH 7.4): 1.00; (6)ACD/KOC (pH 5.5): 8.78; (7)ACD/KOC (pH 7.4): 8.78; (8)#H bond acceptors:3; (9)#Freely Rotating Bonds: 3; (10)Flash Point: 27.778 °C; (11)Enthalpy of Vaporization: 33.446 kJ/mol; (12)Boiling Point: 110.229 °C at 760 mmHg; (13)Vapour Pressure: 28.1490001678467 mmHg at 25°C

Uses of Trimethyl phosphite: Trimethyl phosphite could react with chloro-triphenyl-methane to produce trityl-phosphonic acid dimethyl ester. This reaction could react in the temperature of 140 - 175 ℃.

When you are dealing with this chemical, you should be very careful. For being a kind of harmful chemical, it may cause damage to health. And it is irritating to eyes, respiratory system and skin and it will be very dangerous if swallowed. Therefore, if in case of contact with eyes, rinse immediately with plenty of water and seek medical advice.

You can still convert the following datas into molecular structure:
