四氯乙烷

AFM观察表明在四氯乙烷中分散后的粒径约为50nm，几乎所有颗粒都以原生粒子的状态单独分散，颗粒间无团聚。

The AFM image shows that the particles dispersed in tetrachloroethane are about 50 nm in diameter , and they were almost dispersed homogeneously as original particles without any agglomeration or adhesion .

利用该TiO2溶胶作为光催化剂对水中微量1,1,2,2-四氯乙烷进行紫外光催化处理。

Photo-catalytic degradation experiment of 1,1,2,2-tetrachloroethane was conducted by using TiO_2 as photo-catalyst under ultraviolet light , and was measured by conductivity instrument .

没有检出1,1,1-三氯乙烷、溴仿、1,1,2,2-四氯乙烷。

While 1,1,1-trichloroethane , bromoform , 1,1,2,2-tetrachloroethane are not found .

近年来，以活性炭为催化剂在气相条件下催化四氯乙烷脱氯化氢制三氯乙烯的工艺路线逐渐兴起。

Recently , TEC dechlorination over activated carbon based catalysts in gas-phase is arising .
