Determination of relative reactivity in the epoxidation of propylene dimers and calculation of the composition of the reaction mixture. Dobrev, D.; Kurtev, K. (Vissh. Khim.-Tekhnol. Inst., Burgas, Bulg.). Khim. Ind. (Sofia), 58(9), 390-2 (Bulgarian) 1986. CODEN: KINSAF. ISSN: 0368-5764. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) A mixt. of hexenes, prepd. by dimerization of propylene in the presence of Ni(C5H2O2)2AlCl(C2H5)2-P(C6H5)3, was epoxidized with isopropylbenzene hydroperoxide in the presence of MoO2(C5H7O2)2 at 40, 50, and 60° and different conversion degrees to investigate the reactivity of the dimers during epoxidn. The isomers with substituted double-bond C's had the highest reactivity. Equations describing the concn. of each isomer of hexene and hexene oxide and the total degree of conversion as function of the conversion degree of a key component of the mixt. are given. The equation is also used to calc. the conversion of key components at which the concn. of a given isomer in a resp. fraction reaches a max. 4050-45-7 and 763-29-1 are just another two chemicals used in this study. value. .

Zinc aluminate double bond isomerization catalyst and double bond isomerization of olefins employing said catalyst

Zinc aluminate double bond isomerization catalyst and double bond isomerization of olefins employing said catalyst. Welch, M. Bruce (Phillips Petroleum Co. , USA). U.S. US 4620053 A 28 Oct 1986, 5 pp. (United States of America) CODEN: USXXAM. CLASS: ICM: C07C005-23. NCL: 585664000. APPLICATION: US 85-745556 17 Jun 1985. DOCUMENT TYPE: Patent CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 23, 67 C34 alkenes are isomerized with an activated Zn aluminate at 50-600°. The catalyst is prepd. by calcining Zn aluminate in O at 250-800° for 1-30 h and contacting the calcined catalyst with a reducing gas selected from the group consisting of CO, H, and NO at 400-750° for 1 min-30 h. Thus, 5 g of Zn aluminate (I) extrudate was mixed with 50 mL H2O, the mixt. heated at 90° for 1 h, and the I powder dried at 250° for 1 h. A tubular reactor was charged with 0.There are some commonly used reagents with their cas registry numbers 630-08-0 and 4050-45-7 in this article.71 g I, the reactor was heated in flowing air at 550° for 2 h, catalyst was treated with CO for 30 min at 550°, and the activated catalyst cooled with Ar. The reactor was heated to 400° and 1-hexene was fed to the catalyst at WHSV of 40 producing a 62.31% conversion of the feedstock to 22.76% cis-2-hexene and 39.55% trans-2 and 3-hexenes. .
