Oxime phosphate is prepd. for use as an inseticide. 5.32g of 5- methyl-4-oximino-1,3-oxathiolane, 50ml of acetonitrile, and 6.38g of calcium carbonate are mixed in a reactor and then are reacted 1hr at 55≦̸C and then this reaction mixt. is cooled ot 40≦̸C and 8.10g of O- ethyl-S-n-propyl phosphochloridate is added to the reaction mixt.. This reaction mixt. is reacted 6hrs at 55≦̸C and then is cooled to room temp. and is stirred overnight. After extraction and washing, O- ethyl-S-propyl-O-(5-methyl-1,3-oxathiolane-4-ylimino)- phosphorothioate is prepd..
