    摘要: The present invention relates to crop culture and is particularly concerned with practices for conserving soil nitrogen and for supplying the soil nitrogen requirements for plant nutrition. These practices involve the employment, as active agent, of a novel butane compound having the formula ##STR1## wherein each Y is independently hydrogen, chloro-, bromo-, fluoro- or methyl; Z is a straight or branched chain alkyl of 1-4 carbon atoms; R is C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy or halo and n is an integer from 0 to 2.

    摘要: Compounds are prepared corresponding to the formula ##STR1## WHEREIN R represents hydrogen or methylenethiocyanate (--CH.sub.2 SCN) and each of R.sup.1 and R.sup.2 represents loweralkyl of 1 to 4 carbon atoms. Those compounds wherein R is methylenethiocyanate have been found to be active antimicrobial agents and those wherein R is hydrogen are useful as intermediates therefor.

    摘要: Cyclopropylcyanide is prepared by an improved process comprising reacting by contacting a .gamma.-halo-butyronitrile or mixture thereof, with an alkali metal hydroxide in the presence of a catalytic amount of an onium salt. For example, the reaction of 4-chlorobutyronitrile with sodium hydroxide in the presence of benzyltriethylammonium chloride produces cyclopropylcyanide in high yield.
