Title (EN) LIQUEFACTION OF ACID ANHYDRIDE
(FR) LIQUEFACTION D"ANHYDRIDE ACIDE
Abstract: front page image
(EN)Diels-Alder reaction products of maleic anhydride which is in a solid state in a room temperature and a dimethyloctatriene are liquefied by heat-treatment in the presence of an isomerization catalyst of compounds selected from the group consisting of a) alkali metal salts, b) amines and quaternary ammonium salts, c) phosphine compounds and quaternary phosphonium salts, d) thiocyanates, and e) solid basic compounds. The liquefied acid anhydrides thus obtained are useful as a curing agent for epoxy resins.
(FR)Des produits de la reaction de Diels-Alder d"anhydride malleique a l"etat solide a temperature ambiante et un dimethyloctatriene sont liquefies par traitement thermique en presence d"un catalyseur d"isomerisation de composes choisis parmi le groupe comprenant: a) des sels metalliques alcalins, b) des amines et des sels d"ammonium quaternaire, c) des composes de phosphine et des sels de phosphonium quarternaire, d) des thiocyanates et e) des composes basiques solides. Les anhydrides acides liquefiees ainsi obtenus sont utiles comme agent de polymerisation pour des resines epoxy.
