Abstract

PURPOSE:To provide a hydrocarbon composition comprising n-undecane, n- decane, n-dodecane, a linear aliphatic hydrocarbon and a specific fluorinated hydrocarbon, safe on firing, readily handleable and suitable as a detergent for dry cleaning. CONSTITUTION:The objective composition comprises (A) 20-99.4wt.% of n- undecane, (B) 0-80wt.% of n-decane and/or n-dodecane, (C) 90-98wt.% of a 9-13C linear aliphatic hydrocarbon (preferably 9-13C n-paraffin), and (D) 0.5-5wt.% of a fluorinated hydrocarbon compound selected from Freon 113(R), Freon 22(R), sulfur hexafluoride, trifluoroethanol, hexafluoroacetone and perfluorocarbon. When the perfluorocarbon is used as the component D, a nonionic surfactant or a highly polar solvent is preferably simultaneously used, because the perfluorocarbon is substantially not dissolved in n-paraffin.

2. Description of the Related Art Conventionally, chlorine-based solvents such as trichlene, perclen, and chloroform have been used as a solvent for dry cleaning, a solvent for electronic parts, mechanical articles, etc. because of their poor flammability and safety. However, from the viewpoint of environmental pollution, etc., the use is prohibited. That is, these become trihalomethanes which are carcinogenic substances when released into the air or groundwater, and cause photochemical smog such as oxidants when released into the atmosphere, and further destroy the ozone layer. It has problems such as becoming a source. As an alternative to these cleaning solvents, straight chain aliphatic hydrocarbons mainly containing C 11 have been developed.

The present invention will be described in more detail below. The component (a), n-undecane, used in the present invention is an aliphatic hydrocarbon solvent that has a flash point of 68 to 69 ° C. and is classified into the first petroleum. n-Undecane can be separated with high efficiency by the molecular sieve method, and 98% pure one is commercially available (for example, manufactured by Nippon Mining Co., Ltd.). When used as a solvent for dry cleaning, n-undecane is gentle on fabric and has a good cleaning effect. Further, when the waste solvent is recovered, if it has a single composition, there is an advantage that there is no change in composition during distillative recovery. This compounding amount is 20 to 99.4% by weight, preferably 80 to 98% by weight. n-
If the amount of undecane is less than 20% by weight, the detergency will be poor, and if it exceeds 99.4% by weight, the flash point will be low, which is not preferable.
