Publication number: 20110288240Abstract: A phosphazene-supported catalyst in which a support is bonded to a group represented by the general formula (1): wherein n, Zn?, a, b, c, d, R, R1 and D are all defined. The phosphazene-supported catalyst is highly effective to catalyze various organic reactions, and further has no reduction of activity even after recovery and reuse of the catalyst, thus it being economically advantageous. In addition, the polymerization of cyclic monomers, substitution of substituents, carbon-carbon bond forming reactions and the like can be conducted with extremely high efficiency.Type: ApplicationFiled: August 4, 2011Publication date: November 24, 2011Applicant: Mitsui Chemicals, Inc.Inventors: Naritoshi YOSHIMURA, Shinji Kiyono, Kazumi Mizutani, Isao Hara, Takaomi Hayashi, Tadahito Nobori, Yoshihiro Yamamoto, Miyuki Konno, Yoshihisa Inoue, Akira Matsuura, Tuneyuki Ohkubo

Patent number: 8048189Abstract: Reduced volatility of urea fertilizers are prepared in accordance with the present invention by first preparing an N-(n-butyl)-thiophosphoric triamide (NBPT) solution by dissolving NBPT in a mixture of an amino alcohol having the formula 1—(H)x—N—((CH2)m—OH)n where m is 1-3, x is 0 or 1, and n is 2 when x is 1 and 3 when x is 0: or the formula 2—(H)y—N—((CH2)—CHOH—CH3)z such that the length of the carbon chain where the secondary hydroxyl group is located is 3, y is 0 or 1, and z is 2 when y is 1 and 3 when y is 0, and a carboxylic acid having 6 or fewer carbon atoms. The solution is then combining with a urea fertilizer in granular or liquid form.Type: GrantFiled: February 17, 2009Date of Patent: November 1, 2011Assignee: Whitehurst Associates Inc.Inventors: Garnett B.

Patent number: 7994363Abstract: A new P-N-P ligand in which each phosphorus atom is bonded to two ortho-fluorine substituted phenyl groups is useful in ethylene oligomerizations. In combination with i) a source of chromium and ii) an activator such as methalumoxane; the ligand of this invention may be used to prepare an oligomer product that contains a mixture of hexenes and octenes. The hexenes and octenes produced with this ligand contain very low levels of internal olefins when produced under preferred reaction conditions.Type: GrantFiled: March 20, 2008Date of Patent: August 9, 2011Assignee: Nova Chemicals (International) S.AInventors: Xiaoliang Gao, Charles Ashton Garret Carter, Liangyou Fan, Lee Douglas Henderson
