A cleaning solvent composition comprising an aliphatic fluorohydrocarbon represented by the general formula CnFmH2n+2-m (wherein n and m represent each a positive integer provided that 4 ≦ n ≦ 6 and 2n-3 ≦ m < 2n+2) or a mixture thereof with a C₁-C₄ alcohol and, further added thereto, a lactam and/or a carboxamide, a tertiary amine or an alcohol having an ether linkage and/or an amino linkage in its molecule. A cleaning method comprising removing dirty components by dipping in the above composition, conducting rinsing with the above mixture and thereafter, if necessary, conducting steam cleaning with the mixture. It is possible to obtain a cleaned article free from stain and dirt in a simplified drying step, because rinsing and steam cleaning can be conducted in a nonaqueous system with a cleaning solvent composition which does not destruct ozone, is nonflammable and has a potent detergency.
一种清洁溶剂组合物,包含由通式 CnFmH2n+2-m 所代表的脂肪族
氟烃 (其中 n 和 m 各代表一个正整数,条件是 4 ≦ n ≦ 6 和 2n-3 ≦ m < 2n+2)或其与 C₁-C₄ 醇的混合物,以及、内酰胺和/或羧酰胺、叔胺或分子中具有醚键和/或
氨基键的醇的混合物。一种清洗方法,包括通过浸泡在上述组合物中去除脏污成分,用上述混合物进行冲洗,然后在必要时用混合物进行蒸汽清洗。由于冲洗和蒸汽清洗可在非
水体系中进行,且清洗溶剂组合物不会破坏
臭氧,不易燃且具有强力去污力,因此可简化干燥步骤,获得无污渍和污垢的清洗物品。
