観点より特定フロン同様に生産量規制の動きがある。[Problem to be solved by the invention] When fully halogenated hydrocarbons such as Freon old 1, R12, and R113, which are particularly chemically stable, reach the stratosphere, chlorine radicals decomposed by sunlight and generated undergo a chain reaction with ozone. Due to the fact that these fluorocarbons are harmful to the environment and destroy the ozone layer, the production volume of these specific fluorocarbons has been regulated. Also, l
, l, l- Trichloroethane also contains chlorine, which is said to be a cause of ozone layer depletion, so from the perspective of environmental protection, there is a movement to regulate the production amount, similar to that of specified fluorocarbons.
このため、従来より用いられてきた１，１．１−トリク

有している。The composition of the present invention has an azeotropic composition and, as a cleaning solvent, has the same cleaning power as conventional 1, 1, 1-1-lichloroethane, so it can be used effectively without causing deterioration of the parts to be cleaned. It is possible to carry out thorough cleaning, and the regulated substance l.
1. The amount of 1-1-lichloroethane used can be significantly reduced. In addition, because they have very similar physical properties, they have the advantage of being able to be used in a wide variety of cleaning methods without making major changes to the specifications of equipment such as washing machines that are currently in use. Because i. It is extremely useful as a substitute for l,i-trichloroethane. Furthermore,
It has many advantages, such as little change in composition after recycling.
