FIELD: suppression or reduction of icing on surfaces by means of antiicing compounds. ^ SUBSTANCE: proposed anti-icing compounds contain succinic acid and/or succinic anhydride and neutralizing base, sodium hydroxide, potassium hydroxide or ammonium hydroxide in particular. When mixed with water anti-icing compounds form succinates in the course of reaction which causes fast liberation of heat sufficient for melting ice on surface. According to other versions, anti-icing compounds contain glycol which inhibits repeated icing on cleaned surface. Specification gives description of sets of compounds for melting snow and ice. ^ EFFECT: enhanced efficiency of melting snow and ice on aircraft and territories of their operation. ^ 29 cl, 11 dwg, 7 tbl, 2 ex |
