Perchlorethylene stabilized - universal chlorine solvent, is an effective means for dry dry cleaning of clothes. It can also be used for degreasing metals in mechanical engineering, in the processing of photopolymer printed circuit boards, in the production of freons, needles for disposable syringes, in the textile, woodworking industry, in the production of freons and active dyes. About 60% of all consumed tetrachlorethylene is used as a solvent in dry cleaning. Tetrachlorethylene has replaced all other solvents in this area because it is non-flammable and can be used safely without special precautions. Due to its stability, tetrachlorethylene contains a low percentage of stabilizers and for the same reason is used along with trichlorethylene and 1,1,1-trichloroethane for degreasing metals, especially aluminum. In smaller quantities, tetrachlorethylene is used in the textile industry and the production of freon-113. In oil refining, tetrachlorethylene, along with dichloroethane, is used in the process of oxychlorination (to restore activity) of bimetallic catalysts in catalytic reforming and low-temperature isomerization units.
