Phosphorus-antimony bonds double

A mixture of monolauryl phosphate sodium salt and triethylamine in H20 was treated with glycidol at 80°C for 8 h to give 98% lauryl 2,3-dihydro-xypropyl phosphate sodium salt [304]. Dyeing aids for polyester fibers exist of triethanolamine salts of ethoxylated phenol-styrene adduct phosphate esters [294], Fatty ethanolamide phosphate surfactant are obtained from the reaction of fatty alcohols and fatty ethanolamides with phosphorus pentoxide and neutralization of the product [295]. A double bond in the alkyl group of phosphoric acid esters alter the properties of the molecule. Diethylethanolamine salt of oleyl phosphate is effectively used as a dispersant for antimony oxide in a mixture of xylene-type solvent and water. The composition is useful as an additive for preventing functional deterioration of fluid catalytic cracking catalysts for heavy petroleum fractions. When it was allowed to stand at room temperature for 1 month it shows almost no precipitation [241]. 

Phosphetene, arsetene, stibetene, or bismetene. Four-membered rings with one phosphorus, arsenic, antimony, or bismuth atom and one double bond in the ring are called phosphetene, arsetene, stibetene, or bismetene. These compounds can be named as phosphacyclobutene derivative, etc. The two isomers based on the position of the double bond can be named as A -phosphetene and A2-phosphetene, for example.
