US President George W. Bush planning to push for faster elimination of ozone-damaging chemicals called hydro chlorofluorocarbon, or CFCs. 美國(guó)總統(tǒng)布什計(jì)劃加速管制禁用破壞臭氧層的含氯氟碳化物。

Because of the ozone depletion and green house effect, chlorofluorocarbon (CFC), known as Freon, has been banned to be used in the whole world. 氯氟烷烴(CFC)即氟里昂,因?qū)Τ粞鯇拥钠茐暮蜏厥倚?yīng)而導(dǎo)致禁用,以其為拋射劑的藥用吸入氣霧劑將于2010年全面退出中國(guó)市場(chǎng)。

The method of hydrodechlorination by palladium catalyst is to remove chlorine atom in chlorofluorocarbon and turn it into the possible substitute pentafluoroethane. 以活性炭為載體的負(fù)載型鈀催化劑對(duì)五氟氯乙烷的選擇性加氫脫氯反應(yīng)具有良好的催化活性,色譜分析表明,其生成產(chǎn)物五氟乙烷的選擇性高達(dá)99%25。

The amount of ozone-eating chlorofluorocarbon in the atmosphere is dropping faster than anyone expected;the chemicals should peak around the year 2000,then decline. 在大氣中會(huì)侵蝕臭氧層的氟利昂制冷劑的含量，其降低的速度超出所有人的預(yù)期；這種化學(xué)物質(zhì)的量應(yīng)該在公元2000年達(dá)到高峰，之后才下降。
