Abstract
"COMPOSIçãO AQUOSA REFRIGERANTE". Uma composição aquosa refrigerante composta de i) um sal de acetato metal alcalino estando presente numa quantidade que fornecerá de 5,4 a 31% em peso de acetato por peso de água na composição; e ii) um ou mais sais de um metal alcalino no qual a parte ânionica é escolhida entre um carbonato ou bicarbonato e fosfato ou misturas dos mesmos, o dito metal alcalino estando presente em uma quantidade que fornecerá 0,07 a 9,5% em peso da parte ânionica por peso de água na composição, a composição tendo um pH entre 9 e 12,5."WATER REFRIGERANT COMPOSITION". An aqueous refrigerant composition composed of i) an alkali metal acetate salt being present in an amount that will provide 5.4 to 31% by weight of acetate per weight of water in the composition; and ii) one or more salts of an alkali metal in which the anionic part is chosen from a carbonate or bicarbonate and phosphate or mixtures thereof, said alkali metal being present in an amount that will provide 0.07 to 9.5% in weight of the anionic part by weight of water in the composition, the composition having a pH between 9 and 12.5.
