The predominant microorganisms in samples taken from shower heads in residences in the Korean city "N" were Stenotrophomonas maltophilia, Sphingomonas paucimobilis, Acidovorax temperans, and Microbacterium lacticum. Legionella was not detected in this case. The volatile organic compounds (VOCs) vinylacetate, NN-DMA, cis-1,2-dichloroethylene, epichlorohydrin, and styrene were measured in five ty...

In the article, kinetic laws, kinetics, and mechanism of oxidative acetylation reaction ethylene in vapor phase were studied detail 0.4%Rd+4%Cu+7%CH 3 COOK/YuKTs catalyst. As a result research, following optimal conditions for selected: middle zone reactor at temperature 165°C, volume velocity 2000 h -1 , pressure 4 atm, ratio to acetic acid 4:1 an oxygen content 7% by volume. Under these condi...
