摘要:
A dispersant composition comprising (1) a polysiloxane-polyoxyalkylene copolymer; and (2) an oxyalkylene polymer, in which the oxyalkylene of (1) and (2) is oxyethylene and/or oxypropylene. The composition disperses contaminants in aqueous systems without foaming, and also cleanses fouled surfaces.
摘要:
Alkylation processes catalyzed by liquid strong acid catalysts wherein an alkylatable hydrocarbon is alkylated with an alkylating agent. Hydrocarbon solutions of alkylation aids prepared using alkylphenol solubilizing agents are employed to improve alkylate quality and reduce acid consumption in such alkylation processes. This application is related to application Ser. No. 359,941, filed May 14, 1973, now Pat. No. 3,829,525, which is incorporated herein in its entirety for all purposes.
摘要:
A developer composition for photosensitive coatings on substrates, particularly lithographic printing plates sensitized with substantially water-insoluble diazonium compounds, which is comprised of an aqueous solution of an amphoteric surfactant. The novel developers quickly remove non-image areas of the plate and yet do not detrimentally dissolve the image areas of the plate.
摘要:
Surfactant compositions and baths for specific textile wetprocessing operations are disclosed. The compositions exhibit surfactant qualities even in the presence of up to ten percent (10%) electrolytes including alkalies in the baths and are not adversely affected by water hardness, oxidative reagents or elevated bath temperatures. The compositions include a blend of phosphate esters of 8-carbon alcohols with soluble sulphate esters of alkoxylated alcohols and alkylphenols.
