    摘要： Disclosed is a process for cleaning wellbore walls, tubing or casings. The process is characterized by (a) preparing an aqueous surfactant composition containing from about 10% to 60% by weight of a mixture of surfactants, the mixture comprising from 10% to 50% by weight of an anionic derivative of an alkylpolyglycoside, from 35% to 80% by weight of an alkylpolyglycoside and from 5% to 25% by weight of an anionic derivative of a fatty alcohol, their balance being 100%; (b) diluting the aqueous surfactant composition in water to form a diluted aqueous surfactant composition and injecting the diluted aqueous surfactant composition into a wellbore containing drilling mud, oily residues or other undesirable deposits; (c) extracting from the wellbore the diluted aqueous surfactant composition containing the drilling mud, oily residues or other undesirable deposits; (d) removing the drilling mud, oily residues or other undesirable deposits from the diluted aqueous surfactant composition; and (e) optionally, re-using the diluted aqueous surfactant composition.

    摘要： Titanium sulphate solutions obtained in the sulphate process from titaniferous materials are hydrolized by contacting at 88.degree.-98.degree. C water with a first titanium sulphate solution having a TiO.sub.2 titer of 230-260 g/l and an acid factor of 1.75-1.85, adding at 88.degree.-98.degree. C to the mixture a second titanium sulphate solution having a TiO.sub.2 titer of 230-260 g/l and an acid factor of 2.1-2.4 and heating the resulting mixture at boiling point. A volumetric ratio of from 3:100 to 12:100 is maintained between the first and the second solution.

    摘要： An improved method for synthesizing alkylpolyglucosides comprising reacting a glycoside with a long-chain alcohol in the presence of a novel type of catalyst, constituted by an alkali or aryl sulfonic acid, wherein the sulfonic group is sterically hindered. Using these catalysts, a raw product is obtained which is practically free from byproducts. The resulting alkyl polyglucosides are completely biodegradable surfactants and can be used to formulate detergents.
