Title
(EN) LOW FOAMING FLUIDS HAVING BIODEGRADABLE POLYALKYLENE GLYCOL RHEOLOGY MODIFIERS
(FR) FLUIDES FAIBLEMENT MOUSSANTS AYANT DES MODIFICATEURS DE RHÉOLOGIE DE POLYALKYLÈNE GLYCOL BIODÉGRADABLES
Abstract
(EN) A composition comprising water and a polyalkylene glycol having an allyl content of less than 20 ueq/g, which composition has reduced foaming properties and preferably a biodegradability of at least 60% as determined using OECD 301F. The polyalkylene glycol can be made by forming a first intermediate comprising an oxypropylene block by reacting propylene oxide with a polyol initiator in the presence of a Double Metal Cyanide catalyst, and then reacting the first intermediate with ethylene oxide in the presence of a KOH catalyst.
(FR) L'invention concerne une composition comprenant de l'eau et un polyalkylène glycol ayant une teneur en allyle inférieure à 20 ueq/g, ladite composition ayant des propriétés moussantes réduites et de préférence une biodégradabilité d'au moins 60 % telle que déterminée à l'aide d'OECD 301F. Le polyalkylène glycol peut être obtenu par formation d'un premier intermédiaire comprenant un bloc oxypropylène par réaction d'oxyde de propylène avec un initiateur polyol en présence d'un catalyseur de cyanure métallique double, puis par réaction du premier intermédiaire avec de l'oxyde d'éthylène en présence d'un catalyseur KOH.
