Zusammenfassung:	1315670 Pyrolysis of nickel salts of phosphonic acid monoesters CIBA-GEIGY AG 30 July 1970 [31 July 1969] 36947/70 Heading C2P [Also in Division C3] A pyrolysate is prepared by heating a compound of the Formula I where R 1 and R 2 are each C 1-5 alkyl or 1-methylcyclohexyl, R 3 is C 1-5 alkyl, and x is 0À5 to 3, at 160 to 300 C. and removing the constituents volatile at the temperature of the heat treatment. The heating may be carried out in the presence or absence of an inert solvent. The pyrolysates produced may be used as stabilizers for synthetic polymers (Division C3).
