METHOD OF PRODUCING O-PINAKOLYLMETHYLPHOSPHONATE Russian patent published in 2017 - IPC C07F9/40 

FIELD: chemistry.

SUBSTANCE: in proposed method O-pinakolylmethylphosphonate is obtained with the mass fraction value of the basic substance in the product of at least 96 wt % by decompounding with O-pinacolyl-O'-trimethylsilylmethylphosphonate methanol, which is a product of silylation with O-methyl-O'-pinakolylmethylphosphonate trimethylchlorosilane, obtained by sequential treatment of methylphosphonic acid dichloride in chloroform medium, initially with equimolar mixture of pinacolyl alcohol with triethylamine and then with equimolar mixture of methanol with triethylamine without disengagement and purification of intermediate products.

EFFECT: higher output of O-pinakolylmethylphosphonate suitable for producing state standard sample of its composition, applied for the state metrological control and supervision, monitoring of conditions and labour safety, environmental state, technical process management at the enterprises.
