标题:Process for the manufacture of polylactones derived from poly-α-hydroxyacrylic acids

摘要:Process for the manufacture of polylactones derived from poly-α-hydroxyacrylic acids comprises heating a liquid aqueous solution of α, β-dichloropropionic acid to a temperature above 100°C to convert the α,β-dichloropropionic acid to the corresponding α-chloroacrylic acid and polymerizing the α-chloroacrylic acid in the aqueous solution in the presence of a polymerization catalyst to polymerize, hydrolyze and lactonize the α-chloroacrylic acid. n The products obtained can be used as intermediates for the synthesis of salts of poly-α-hydroxyacrylic acids.

摘要:A process is described for the preparation of concentrated liquid formulations, stable on storage, of anionic fluorescent brighteners, which process consists in passing a crude (for example obtained from synthesis) aqueous solution or dispersion of a fluorescent brightener containing sulfo groups, in particular a stilbene fluorescent brightener belonging to the group comprising bistriazinylaminostilbenedisulfonic acids, bis-styrylbiphenyls, bis-styrylbenzenes and bis-triazolylstilbenedisulfonic acids, is passed through a semipermeable membrane which contains ionic groups and has a pore diameter of 1-500 ANGSTROM in order to remove salts and by-products from the synthesis having molecular weights below 500 and in order to remove part of the water. The resulting concentrated preparation can, if desired, be concentrated further and/or treated with formulation assistants and, if desired, further additives.

标 题:Process for the preparation of solid composition of water-soluble dyes
发明人：BRUTTEL BEAT; PFENNINGER HEINZ
权利人:CIBA GEIGY CORP
摘要:A process for producing solid dye compositions, which process comprises passing an aqueous solution or suspension of at least one water-soluble crude dye, to effect separation of synthesis by-products having a molecular weight of below 500 and partial separation of water, through a semipermeable membrane, subsequently drying the resulting aqueous preparation which has become more highly concentrated, and optionally adding further additives before and/or after passage of the aqueous solution or suspension through the semipermeable membrane, these additives being added beforehand only when they do not become separated by the membrane. There are obtained by this process low-dust to dust-free compositions which are distinguished by high mechanical strength, high bulk density, free-flowing characteristics and good dissolving behavior. Employing these compositions it is possible to prepare low-foam to foam-free aqueous dye liquors having very good solution stability, even in the presence of electrolytes.

权利人:CIBA GEIGY CORP
摘要:A process for the preparation of storage-stable concentrated fluid dye compositions of water-soluble dyes, wherein an aqueous solution or suspension of at least one anionic crude dye is passed over a semi-permeable membrane containing ionic groups and having a pore diameter of 1 to 500 ANGSTROM , to remove salts and synthesis by-products of molecular weights less than 500 and to partially remove water, optionally dried, and mixed with a water-miscible organic solvent and, if desired, further additives, before and/or after passage over the semi-permeable membrane. The fluid dye compositions obtained are particularly suitable for use in spray solutions for dyeing leather, as well as for the dying and printing of textile materials, in particular cellulosic fibres.
