摘要:
Included are halogenated phosphate-phosphites and their acid halides and acids. The halogenated phosphate-phosphites can be prepared by a process comprising serially contacing(A) a phosphorus trihalide with a triol;(B) a halogenating agent; and(C) an oxirane or an alcohol;under conditions sufficient to prepare the halogenated phosphate-phosphite. Steps (A) and (B) can prepare their acid halides. Use of water in step (C) can prepare their acids. For example, 3-((bis(2-chloroethoxy)phosphino)oxy)(2-bromoethyl-2-methylpropyl, 2-bromoethyl, 2-chloroethyl)phosphorate can be prepared from 2-methyl-2-(hydroxymethyl)-1,3-propanediol; phosphorus trichloride; bromine; and ethylene oxide.Also included is use of the compounds as a hyraulic fluid or flame retardant. For example, polyurethanes can be rendered less flammable with the halogenated phosphate-phosphite flame retardant.

Included is a process for the preparation of a ((neocarbyl)contrasting-halo-substituted)phosphorate comprising serially contacting (1) a phosphorus trihalide with a neocarbyl alcohol; (2) an oxirane; (3) a halogenating agent; and (4) an oxirane, under conditions sufficient to prepare the ((neocarbyl)contrasting-halo-substituted)phosphorate.The phosphate can be very pure.Also included is a method for improving a production characteristic of flame-retardant polyurethanes. The characteristic may be selected from the group consisting of (1) processability; (2) scorch; (3) odor; (4) flame-retardant efficiency; and (5) combinations thereof. The method comprises incorporation into a polyurethane an amount effective to reduce combustibility of the foregoing phosphorate flame retardant under conditions sufficient to improve said characteristic. Also included is the flame-retardant polyurethane composition of said method. Preferably, the polyurethane is a foam, especially a flexible foam and most especially flexible slabstock foam.
