Publication number: 20140088327Abstract: A process of oxidizing cyclohexane, comprising feeding cyclohexane, an aqueous hydrogen peroxide solution and optionally an organic solvent into a reaction zone through a feed inlet thereof under the oxidation reaction conditions for contact, and providing all or most of the oxidation product at the reaction zone bottom, wherein a part or all of the packing in the reaction zone is a titanium silicate molecular sieve-containing catalyst. The process of oxidizing cyclohexane according to the present invention carries out the oxidation in the reaction zone, which, firstly, utilizes the latent heat from reaction sufficiently so as to achieve energy-saving; secondly, increases the yield of target product and the availability of oxidizer; and thirdly, allows the separation of the oxidation product from the raw material cyclohexane as the reaction proceeds, such that the cost for subsequent separations can be saved.Type: ApplicationFiled: May 2, 2012Publication date: March 27, 2014Applicant: CHINA PETROLEUM & CHEMICAL CORPORATIONInventors: Min Lin, Chunfeng Shi, Bin Zhu, Yingchun Ru

Publication number: 20110054176Abstract: A quinoline-oxazoline compound having the formula: where one of X1 and X2 is N and the other is C and one of R1, R2 and R3 is Z wherein Z is an oxazoline radical having the formula such that when X1 is N R2 is Z and R1 is absent, and when X2 is N either R1 or R3 is Z and R2 is absent. R1 and R3 through R12 are independently H or a pendant moiety which does not interfere with coordination of either N in the quinoline compound with a coordination center. These compounds can be complexed with a suitable coordination center such as catalytically active palladium and can be highly useful in catalytically oxidizing alkenes with high regioselectivity.Type: ApplicationFiled: September 3, 2009Publication date: March 3, 2011Inventors: Matthew Scott Sigman, Brian William Michel
