Abstract

The invention discloses an organic snow-melting agent and a preparation method thereof and belongs to the technical field of applied chemistry.The organic snow-melting agent is prepared from, by mass, 1.5-15% of calcium succinate, 15-30% of magnesium succinate, 3-25% of calcium glutarate, 25-50% of magnesium glutarate, 1-10% of calcium adipate and 10-20% of magnesium adipate.The preparation method of the organic snow-melting agent comprises the following steps of 1, preparing a mixed diacid aqueous solution; 2, calculating and weighing the actual adding volume of salinization reagent; 3, conducting mixing; 4, conducting filtering; 5, conducting decolouration treatment; 6, conducting evaporation for separation.The prepared novel non-chlorine-salt type organic snow-melting agent is mixed with diacid calcium and magnesium and is applicable to snow melting and deicing of places with the temperature being 15 DEG C or above, compared with snow-melting agents of the same type, namely calcium acetate and magnesium acetate, which are commonly used on the market, the applicable temperature range is broadened by about 5 DEG C, and the corrosion damage effect is extremely small; a new path is opened up for recycling of a byproduct, namely mixed diacid, in the nylon production industry, resources are saved, and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of applied chemistry, and in particular relates to an organic deicing agent and a preparation method thereof. Background technique [0002] Deicing agent is a kind of chemical substance that can make ice and snow melt into liquid below 0 ℃, there are solid and liquid. The deicing agent achieves the purpose of melting snow and ice by lowering the freezing point of water so that the water does not condense into a solid state within a certain temperature range below zero. It is used for snow removal in winter on roads, airports, railways, squares and other places, reducing the slippery road surface and improving the safety of vehicles driving on the road surface. Safety, to ensure the smooth flow of traffic and the safety of people's lives and property. In the 1950s, Europe and the United States first started to use deicing agents. At present, the most widely used deicing agents at home and abroad are chlorine...
