Role of water in the partial oxidation of propane to acrylic acid over Mo1V0.3Te0.23Nb0.12Ox catalyst
Effects of water on the catalytic performances of MoVTeNbO catalyst in the oxidation of propane to acrylic acid have been investigated at different reaction temperatures and different steam contents. Obtained results show that both catalytic performances and catalyst structure are very sensitive to the presence of water vapor in the reaction feed. Presence of water induces some structural modif...
متن کاملCholic acid–quinoxaline (2/1)
In the title inclusion compound, 2C(24)H(40)O(5)·C(8)H(6)N(2), the unit cell contains two mol-ecules of cholic acid (3α,7α,12α-trihydr-oxy-5β-cholan-24-oic acid) and one mol-ecule of quinoxaline which implies disorder of the quinoxaline in the space group P2(1). The amphiphilic mol-ecules of cholic acid assemble, in an anti-parallel arrangement, via O-H⋯O hydrogen bonds, into typical corrugated...

متن کاملThe Determination of Cholic Acid in Bile*
In attempting to apply the method described by Gregory and Pascoe (1929) to the determination of bile acids in bile, considerable difficulty was experienced because of the weakness of the blue color developed by cholic acid. Later it was found that because of a misprint in the original paper only one-fifth of the required amount of cholic acid was being used. Before this was known several attem...
متن کاملBacterial 7-dehydroxylation of cholic acid and allocholic acid.
An obligate anaerobic organism capable of dehydroxylating cholic acid to deoxycholic acid and allocholic acid to allodeoxycholic acid was isolated from feces of the rabbit. It was a member of the bacteroides group (Gram-variable, nonsporulating anaerobes). The growth of the organism was inhibited by neomycin, 10-20 micro g/ml. The existence of this organism affords a satisfactory explanation fo...
