Abstract

1280118 Preparing vegetable phosphatides KNAPSACK AG 27 July 1970 [28 Aug 1969] 36304/70 Heading C2P The invention comprises epoxyalkylphosphine oxides of the general formula wherein R 1 and R 2 are selected from C 1 -C 5 alkyl radicals and aryl radicals and R 3 , R 4 and R 5 represent a hydrogen atom or a C 1 -C 5 alkyl radical. They may be obtained by reacting at about 20‹ to 100‹ C., if desired, in the presence of an inert diluent, a secondary phosphine oxide of the general formula (R 1 )(R 2 )P(O)H with a compound of the formula wherein Hal is halogen, e.g. Cl or Br to form an addition product of the formula and dehydrohalogenating the latter, e.g. by contacting with a dehydrohalogenation agent, e.g. an alkali or an organic base, at between about 20‹ and 65‹ C. The process may be carried out in one step without isolation of the intermediate addition product (III) or in two steps by first isolating the product (III) and then dehydrohalogenating in a second step, e.g. by first recrystallizing (III) and then dropping a solution thereof, e.g. in methanol, into an alcoholic solution of an alkali metal hydroxide, e.g. a solution of KOH in methanol, with subsequent removal of the halide formed. Specified dehydrohalogenating agents are NaOH, KOH, Na 2 CO 3 , alkali metal alcoholates, pyridine, triethylamine, 1,5 - diazabicyclo[6,3,0]- undecene and 1,5 - diazabicyclo[4,3,0]nonene and specified diluents are diethyl ether, ethyl acetate and methanol.
