摘要：To replace the cleaning compositions based on 1,1,2-trichloro- 1,2,2-trifluoroethane (F113), the invention proposes a composition comprising by weight 55 to80 % of 1,1-dichloro-1-fluoroethane (F141b) and 45 to 20 % of methyl formate. Thesetwo compounds form a positive azeotrope (b.p. = 28.4 DEG C at normal pressure). …Thecomposition, if necessary stabilised, can be used for the cleaning of solid surfaces, inparticular for the defluxing of printed circuits and for the degreasing of mechanicalcomponents.
