Abstract
A composition for neutralizing or removing an acid in a refrigeration or air-conditioning system, the composition comprising a) an acid neutralizer or scavenger such as a metal alkoxide, carbodiimide, glycidyl ether, epoxide, alkanolamine, arylamine, overbased metal sulphonates, or an inorganic base (e.g. KOH); and b) a hydrolytic drying agent such as an orthoester (e.g. triethylorthoformate), acetal, epoxide, or a carbodiimide, whereby the water formed by neutralization is removed from the system. Also disclosed is the use of the composition for neutralizing or removing an acid from a refrigeration or air-conditioning system; and a method for neutralizing or removing an acid from the refrigeration or air-conditioning system.IPC Classes ?
