Stabilising unsatd. chlorinated acid and ether derivs. - against decomposition by heat and catalysts, using alkali metal salts, esp. phosphate(s), fluoride(s) or carbonate(s) |
摘要 |
<p>Unsatd. cpds. of formulae C3HmClnCOR (I) and C3Cl4C(Cl)OR' (II) are stabilised against decomposition by heat and catalysts with acid or neutral alkali phosphates, fluorides or carbonates. In the formulae, n = 5-m; m = 0 or 1; R is Cl, OH or OR"; R' is C2H5, C3H7 and C4H9; R" is linear, branched or cycloaliphatic, opt. halogenated and/or unsatd., 1-10C alkyl, or aryl or aralkyl (6-14C in aryl) opt. substd. by alkyl or halo. Pref. up to 5% of the alkali salt is added (based on wt. of (I) and (II)). (I) and (II) are intermediates, e.g. 1-ethoxypentachlorobutadiene can be converted to squaric acid or pentachlorovinyl acetyl chloride, the latter convertible to its esters which are 'reactivators' in e.g. ethylene/alpha-olefin copolymer prodn.</p> |
