我国在氟利昂代用品研究领域获重大进展。中科院上海有机化学研究所最近在国内首次合成了氟利昂代用品——F134a,其纯度达99.98％。该所在6月份对3台未改动其任何结构的国产家用电冰箱,进行了灌注F—134a致冷剂试验,至今运转正常。有机所合成的F—134a经清华大学测试表明,其热工性能和国外报道完成一致。据称,去年生效的控制消耗臭氧层的物质的蒙特利尔协定书规定,从1997年起,各国
My country has made significant progress in the field of Freon substitutes research. Chinese Academy of Sciences Shanghai Institute of Organic Chemistry recently in the country for the first time synthesized Freon substitute - F134a, the purity of 99.98%. In June, the institute conducted perfusion F-134a refrigerant tests on three domestic refrigerators that have not changed any of its structures and has operated normally so far. Organic synthesis of F-134a by Tsinghua University tests show that its thermal performance and foreign reports are completed. Allegedly, the Montreal Protocol to Control Ozone Depleting Substances, which entered into force last year, stipulates that since 1997, all countries
