(EN) Fire-resistant plastisols and fire-resistant plasticised polymer compositions, particularly polymer compositions wherein the polymer is derived from a halogen-substituted olefin such as PVC, containing a fire-retardant additive which is a hydrocarbyl polyhaloalkanoate wherein the polyhaloalkanoic acid from which the hydrocarbyl polyhaloalkanoate is derived has at least four carbon atoms and bears at least two halo- substituents, wherein the hydrocarbyl group is preferably aryl and wherein the halo- substituent is preferably chloro-.(FR) La présente invention concerne des plastisols ignifuges et des compositions polymères plastiques ignifuges et particulièrement des compositions au polymère dans lesquelles le polymère est dérivé d'une oléfine à substitution halogène telle que le polychlorure de vinyle. Ces compositions contiennent un produit retardant, à savoir un hydrocarbyle polyhaloalcanoate, l'acide polyhaloalcanoïque dont l'hydrocarbyle polyhaloalcanoate est dérivé comportant au minimum quatre atomes de carbone et portant au moins deux substituants halo-, le groupe hydrocarbyle étant de préférence un aryle, et le substituant halo- étant de préférence chloro-.
A FACILE SYNTHESIS OF α,α,γ-TRICHLOROALKANOIC ACIDS VIA THE Ru(II)-CATALYZED ADDITION OF TRICHLOROACETYL CHLORIDE TO OLEFINS
α,α,γ-Trichloroalkanoic acids were prepared with great ease by the dichlorotris(triphenylphosphine)ruthenium(II)-catalyzed addition of trichloroacetyl chloride to olefinic compounds followed by hydrolysis of the resulting 1:1 adducts, α,α,γ-trichloro-substituted acid chlorides.
通过二氯三(三苯基膦)钌 (II) 催化将三氯乙酰氯加成到烯烃化合物中,然后水解所得的 1:1 加合物 α,α,γ-三氯,可以非常容易地制备 α,α,γ-三氯链烷酸-取代的酰氯。
