    摘要: A process for improving the soil release properties of dishwashing machine rinse aid compositions used to rinse dishware and remove starch-containing soils therefrom by adding to the compositions a cationic polymer containing monomer units corresponding to formula I: ##STR1## in which R.sup.1 is hydrogen or a methyl group,R.sup.2, R.sup.3 and R.sup.4 are the same or different and represent hydrogen or a C.sub.1-8 alk(en)yl group, R.sup.8 is a linear, cyclic or branched alkylene group containing 2 to 8 carbon atoms, andX represents a monofunctional anion or the 1/m part of an m-functional anion.

    摘要: Substituted diphenols, phenyl ethers containing two oxygen atoms attached to a benzene nucleus, and naphthols are more practically effective than previously known additives in stabilizing tin (II) salts, in electrolyte solutions useful for coloring anodized aluminum by electrolysis therein, against oxidation to tin(IV) by reaction with ambient oxygen. Preferred additives include 2-tert-butyl-1,4-dihydroxybenzene, methylhydroquinone, trimethylhydroquinone, 4-hydroxynaphthalene-2,7-disulfonic acid, and p-hydroxyanisole. If p-toluenesulfonic acid or napthalene sulfonic acid are also used in the electrolyte, the throwing power can be greatly improved.

    摘要: Described is a method of recycling the sludge which arises during the zinc phosphating of steel surfaces. The sludge is preferably digested with nitric acid, the iron selectively extracted from the digested solution with liquid/liquid extraction and the extract thus obtained reused in the preparation of zinc phosphating solution. The preferred extraction solvent is a solution of the monoester of 2-ethylhexyl alcohol with phosphoric acid in kerosene.
