Method for the esterification of P-O components

The present invention is directed to a new method for esterification of P-O components. More specifically, the present invention relates to a new method for esterification of P-O components containing at least one P-O-H functional group, whereby the P-O-H functional group(s) is converted into P-O-R functional group(s). The method according to the invention may find particular use in the manufacture of diesters of phosphorous acid.

GELLED HYDROCARBONS FOR OILFIELD PROCESSES, PHOSPHATE ESTER COMPOUNDS USEFUL IN GELLATION OF HYDROCARBONS AND METHODS FOR PRODUCTION AND USE THEREOF

Phosphate esters useful for gelling hydrocarbons in combination with a metal source are disclosed along with methods of preparation of the phosphate esters. Fouling in oil refinery towers has been attributed due to distillation of impurities present in phosphate esters used to gel hydrocarbons for oil well fracturing. The improved method of preparation of the phosphate ester results in a product that substantially reduces or eliminates volatile phosphorus, which is phosphorus impurities that distill up to 250° C., and increases the high temperature viscosity of the hydrocarbon gels formed using the phosphate esters.

Novel approach to the synthesis of AZT 5′-O-hydrogen phospholipids

A series of AZT 5′-O-hydrogen phospholipids were synthesized by a tandem transesterification of diphenyl phosphite with AZT and a long-chain alcohol. The method possesses the merits of ease of operation and high yields. It can also be extended to synthesize other biological phospholipids.
