    • Novel polyfunctional compounds and a novel process for their preparation are disclosed. These compounds may be converted into the acid or salt forms of cis and trans aconitic acids as well as into a racemic mixture of isocitric acid, alloisocitric acid and the lactones of isocitric acid and alloisocitric acid and their salts. All of the acid and salt forms produced are useful as metal sequestrants and/or detergent builders. The novel polyfunctional compounds can also be saponified to their corresponding alkali metal salts which, in turn, are also metal ion sequestering agents and detergent builders. The polyfunctional compounds are the reaction products obtained from the reaction of selected salts of monoalkyl esters of maleic acid with selected active hydrogen containing compounds.
    • 公开了新型多官能化合物及其制备方法。 这些化合物可以转化为顺式和反式乌头酸的酸或盐形式,以及异柠檬酸,异亚油酸和异柠檬酸和异亮氨酸及其盐的内酯的外消旋混合物。 生成的所有酸和盐形式可用作金属螯合剂和/或洗涤剂助洗剂。 新型多官能化合物也可以皂化成相应的碱金属盐,其又是金属离子螯合剂和洗涤剂助洗剂。 多官能化合物是从所选择的含活性氢化合物的马来酸单烷基酯的选择盐的反应获得的反应产物。

    • Acetals of the formulas CHCl.sub.2 CH(OR).sub.2, CCl.sub.3 CH(OR).sub.2, .sub.2 CH(OR).sub.2, CF.sub.3 CH(OR).sub.2, RO.sub.2 CCH(OR).sub.2, and (RO).sub.2 HCCH(OR).sub.2 wherein R can be --CH.sub.2 CYZ(NO.sub.2), --CH.sub.2 CH.sub.2 CYZ(NO.sub.2), --CH.sub.2 C(N0.sub.2).sub.2 CH.sub.3, --CH.sub.2 C(NO.sub.2).sub.2 CYZ(NO.sub.2), --CH.sub.2 C(NO.sub.2).sub.2 CH.sub.2 CYZ(NO.sub.2) or --CH.sub.2 C(NO.sub.2).sub.2 C(NO.sub.2).sub.2 CYZ(NO.sub.2) wherein Y and Z vary independently and can be Cl, F or NO.sub.2. These acetals are produced by contacting a negatively substituted aldehyde such as CHCl.sub.2 CHO, CCl.sub.3 CHO, CHF.sub.2 CHO, CF.sub.3 CHO, HO.sub.2 CCHO, or OHCCHO with a negatively substitute alcohol of the formula ROH wherein R is as defined above. Either FSO.sub.3 H, ClSO.sub.3 H, or CHF.sub.2 SO.sub.3 H, or CF.sub.3 SO.sub.3 H is used to catalyze the condensation. The acetals of this invention are useful as explosives.
