The cyclopentane we produced contains no olefin and very few sulphur, heavy element and benzene. With the high purity, it is used to replace CFCS, which will damage atmospheric ozone layer. Now it has been widely used in the fields of Freon-free refrigerator, freezer industry, refrigeration storage, and pipe line heat preservation. As the days of forbidding using ODS in conventions like Montreal approaching, CFCS and HCFCS will be out of use, and cyclopentane will surely be the most used products in the field of polyurethane foaming agent。
