Abstract

Oppfinnelsen angår anvendelse av en vandig løs- ning av en lavere alkohol med en tilsetning av (1) en polykarboksylsyre av lav molekylvekt, (2) en ester eller salt av sorbinsyre, (3) en flerverdig alko- hol, (4) en alifatisk syre eller et salt av en alifatisk syre, (5) et anionisk tensid og/eller (6) en svovelfri triazolforbindelse som kuldebærermid- del. Oppfinnelsen angår videre anvendelsen av høydispergerbar kiselsyre som sedimentasjons- hemmer i vandige løsninger av lavere alkoholer, som tjener som flytende isblandinger.The invention relates to the use of an aqueous solution of a lower alcohol with the addition of (1) a low molecular weight polycarboxylic acid, (2) an ester or salt of sorbic acid, (3) a polyhydric alcohol, (4) an aliphatic acid or a salt of an aliphatic acid, (5) an anionic surfactant and / or (6) a sulfur-free triazole compound as a refrigerant. The invention further relates to the use of high-dispersible silicic acid as a sedimentation inhibitor in aqueous solutions of lower alcohols, which serve as liquid ice mixtures.
