The synthetic process of new unpolluted melting snow and/or antifreeze agent with natural ore and acetic acid as raw materials is studied by orthorhombic test. The most suitable conditions are determined as follows. The mass ratio of ore to acetic acid solution is 1.2, the concentration of acetic acid is 2.6mol/L, the reaction temperature is 80℃ and the reaction time is 4～6h. The mechanism, effect, influence on the environment, corrosion and loxicity of this melting snow and/or antifreeze are presented.
