    Abstract: 1380961 Azodicarbonamide/sulphinic acid or salt as blowing agents BAYER AG 18 Jan 1972 [18 Jan 1971] 2281/72 Headings C3C and C3R Cellular natural or synthetic rubber or synthetic resins are made using as blowing agent azodicarbonamide together with an activator which is an aromatic sulphinic acid or salt of Formula (I) where M is H, a metal or an ammonium radical which may be substituted, n is the valency of M, and R 1-5 are H, C 1-4 alkyl or halogen. The polymer may be derived from butadiene, chlorobutadiene, dimethylbutadiene, isoprene, styrene, α-methylstyrene, acrylonitrile, methacylonitrile, acrylates, methacrylates, ethylene, propylene, vinyl chloride, and/or vinyl acetate; or may be a polyurethane. The activator may be a benzene sulphinate or sodium, zinc, lead cadmium, magnesium; a p-chlorobenzene sulphinate of zinc or sodium; a toluene sulphinate of cadmium or sodium; or p-chlorobenzene sulphinic acid.

    Abstract: 1340824 Benzthiazolone derivatives and their preparation BAYER AG 12 Jan 1972 [12 Jan 1971(2)] 1387/72 Heading C2C Benzthiazolones of the formula wherein R 1 is an electronegative radical, R 2 is alkyl or an electronegative radical, R 3 is hydrogen, hydroxyl, alkoxy or an aliphatic or cycloaliphatic hydrocarbon radical, R 4 is a radical of the formula -COR 5 , -COOR 6 -CONR 7 R 8 , -SO 2 R 9 or hydrogen, R 5 is hydrogen, optionally substituted alkyl, alkenyl or optionally substituted phenyl, R 6 is alkyl or phenyl, R 7 is hydrogen, alkoxyalkyl, alkenyl or other aliphatic hydrocarbon radical, aralkyl, aryl, cycloalkyl or hydroxy alkyl, R 8 is hydrogen (except when R 7 is hydrogen), alkyl or alkenyl, or R 7 and R 8 , together with the nitrogen to which they are attached, form a heterocyclic ring (which may be interrupted by at least one further heteroatom), R 9 is optionally substituted alkyl, optionally substituted phenyl or dimethylamino, and a is 1 or 2, may be prepared, in the case where R 4 is other than hydrogen, by reacting a benzthiazolone of the formula with (a) an acid chloride of the formula R 6 -CO-Cl, (b) a chloroformic acid alkyl or phenyl ester of the formula R 6 O-CO-Cl, or (c) a sulphonyl chloride of the formula R 9 -SO 2 -Cl, or by reacting a 2-carbamylbenzthiazole-N-oxide of the formula with phosphorus oxychloride. The above reactions may be carried out at -10‹ to +80‹ C. employing the reactants in substantially stoichiometric proportions and reactions (a), (b) and (c) are preferably effected in the presence of an acid-binding agent in an inert organic solvent. Compounds of Formula (I) wherein R 4 is hydrogen may be obtained by reacting a compound of formula with phosphorus oxychloride, preferably at 20-160‹ C. in an inert organic solvent. Electronegative radicals specified are nitro, trifluoromethyl, trifluoromethoxy, chlorine, bromine, iodine, fluorine, cyano, aldehyde, keto, carboxyl and radicals of the formula -SO 2 Y, wherein Y denotes an aliphatic, cycloaliphatic, araliphatic or aromatic radical, fluorine, or an optionally substituted amino group. The compounds of Formula (I) possess insecticidal, acaricidal and fungicidal properties and they may be formulated in compositions of the conventional type and applied in a known manner.
