*Required Fields

Acidulants for dyeing: Acidulants for dyeing. Currie, Andrew Christopher (BP Chemicals Ltd., UK). Brit. UK Pat. Appl. GB 2132641 A1 11 Jul 1984, 4 pp. (English). (United Kingdom). CODEN: BAXXDU. CLASS: IC: D06P001-64. APPLICATION: GB 83-22234 18 Aug 1983. PRIORITY: GB 82-24388 25 Aug 1982. DOCUMENT TYPE: Patent CA Section: 40 (Textiles) Ethylene glycol diformate [629-15-2] and propylene glycol diformate [53818-14-7] are used as additives in dyeing and printing of textiles to gradually regulate the pH from a neutral/alk. medium to acid. They are safer to use and are less volatile and corrosive then the usual acids.

Propylene oxide: Propylene oxide. Haack, Horst; Stoss, Werner; Voigt, Dietrich; Werner, Wilfried (VEB Leuna-Werke "Walter Ulbricht", E. Ger.). Ger. (East) DD 126493 20 Jul 1977, 13 pp. (German). (German Democratic Republic). CODEN: GEXXA8. CLASS: IC: C07D301-06. APPLICATION: DD 76-194005 22 Jul 1976. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Liq.-phase oxidn. of propylene (I) [115-07-1] in a solvent mixt. consisting of propylene glycol mono- [1331-12-0] and diacetate [623-84-7] and propylene glycol mono- [64202-75-1] and diformate [53818-14-7] provides good selectivity for I oxidn. to propylene oxide (II) [75-56-9] and easy sepn. of the oxidn. product from the solvent which could be reused without purifn. Thus, I was oxidized at 180° and 120 atm in a solvent mixt. contg. propylene glycol diacetate 78.8, propylene glycol diformate 2.6, propylene glycol monoacetate 12.1, propylene glycol monoformate 6.4, and propylene glycol (III) 0.1 vol. %. I conversion was 25.7 mol %; the product contained I 44.3, III 2.6, propylene glycol esters (acetate and formate) 14.3, HOAc 11.3, HCO2H 8.4, and CO and CO2 10.9 mol %.
