摘要:
An improved process for dyeing or printing water-swellable cellulosic fibers and mixtures of said cellulosic fibers with synthetic fibers by contacting the fibers throughout with a dye liquor or print paste which contains, as essential ingredients, water in an amount sufficient to swell the cellulosic fibers, a water-insoluble disperse dye and a water-soluble solvent which maintains swelling of the cellulose if water is removed and which is a solvent for the disperse dye, and heating the contacted fibers to effect fixation of the dye, the improvement comprising using as water-soluble solvent a mixture of(a) polyethylene oxide, a block copolymer of ethylene oxide and propylene oxide or an ether, ester or carbamate derivative thereof and(b) a polyoxyethylated amine.

摘要:
Fuels for internal combustion engines or lubricants contain small amounts of polyisobutylaminoalcohols of the formulae Ia and Ib where R is polyisobutyl having a number average molecular weight of 500 to 5,000 and in each of the two formulae one of the radicals X is OH and the other is the group where the radicals R1 may be identical or different and are each hydrogen, alkyl, hydroxyalkyl or aminoalkyl which may be substituted by further hydroxyl- or amino-carrying alkyl radicals, or the two radicals R1 may form a nonaromatic ring.
