    Abstract: Org. pigments for dyeing plastics were manufd. by adding homopolymers or copolymers of monomer contg.CH2=CH- or CH2=CR to the reaction mixt. used for prepg. the pigment. The mixt. for the pigment was obtained by coupling diazotized 2-nitroaniline-4-sulfonic acid with acetoacet-o-chloroanilide in the presence of theor. amt. CaCO3.

    Abstract: Title compds. (I; Z1 = II; R1 and R2 are C1-4 alkyl; X = -0-, -NH-; Y = O, S, C1-4 alkyl, benzyl; n = 0-1; A = -CH2- CH2-; Z2 and Z3 are same or not, -NR3R4, -OR5, -SR6, R3 and R4 are same or not, H, lower alkyl, benzyl; R5 = lower alkyl residue; R6 = C1-8 alkyl residue) were prepd. by the reaction of cyanurine halide and IV. Thus, 28.2 g 2,2,6,6-tetramethyl-piperidin-4-ol and 4.2 g natrium were stirred for 18 hr in xylene, followed by addn. of 10.1 g cyanurine chloride, and refluxed 1 hr to give 23.7 g cyanurine chloride, and refluxed 1 hr to give 23.7 g 2,4,6-tris[2',2',6',6'-tetramethylpiperidinyl-4'-oxy -1,3,5-triazine.

    Abstract: Title compds.[I; R1 = C1-10 alkyl, C1-2 alkoxy - C1-2 alkyl, cyclohexyl group; R2 = C1-4 alkyl; Z = halogen, (CH3)-NCOX1 (X1 = halogen); Y = H, IV , useful as insecticide, were prepd. by reaction of compd. (II) and compd. (III) in the presence of base. Thus, the mixt. of methylene chloride 70 ml, methyl-N-n-butyl urethane 8.5 g, SCl2 8.7g, and triethylamine 7.1 g was stirred for 30 min at 0-5oC, suspended in the petroleum ether and then filtered to give intermediate. The intermediate was added in the methylene chloride 70 ml soln. at 5-10oC and stirred for 12 hr. after dropping pyridine 7g. The reactant was suspended in the benzene, filtered and distilled to give I.

    Abstract: Title compds. (I; n = 1 or 2; Ra, Rb = C1-6 alkyl; Rc = C1-9 alkyl or PhCH2; Rd = C1-6 alkyl; Rc,Rd = tetra or pentamethylene; R3, Rf = H or C3-4 alkenyl; X = O or NR; R = H or C7-9 aralkyl; R1 = H or CH2CH(OR5)R4; R4 = Me or Ph; R5 = H or ACO; A = C1-12 alkyl, Ph, or a ph or phenylethyl subtd. by two C1-4 alkyl and OH; R2 = a group of formula(III); R6, R7 = C1-9 alkyl or C7-9 aralkyl; R8 = H or Me) useful as stabilizers which protect plastics against degradation by O2 heat and light, were manufd. by reaction of II and n mole hydroxybenzyldithiocarbonate.
