Reaction Steps

The coolant composition of the present invention can be prepared by merely mixing the components (A), (B) and (C) each in a specified amount to give a uniform mixture. In an actual procedure, it is advantageous that sodium benzoate as the component (B) is first dissolved in water as the component (C) to give a uniform aqueous solution of sodium benzoate into which liquid 1,6-hexanediol prepared in advance by heating the solidified compound having a melting point of about 43° C. is added as the component (A) under agitation with a suitable stirrer. It is important in this case that entrainment of air into the mixture under agitation is minimized in order to avoid increase of the dissolved oxygen therein by adequately selecting the types of the stirrer blades and the velocity of stirrer revolution.
