Preparation of heat-resistant viscosity reducer

Preparation of heat-resistant viscosity reducer. Ge, Jijiang; Zhang, Guicai; Sun, Mingqin; Song, Zhaozheng (University of Petroleum East China, Peop. Rep. China). Faming Zhuanli Shenqing Gongkai Shuomingshu CN 1560177 A 5 Jan 2005, 5 pp. (Chinese). (People's Republic of China). CODEN: CNXXEV. 4763-40-0 is the cas registry number of certain chemical which is used as reagents here. CLASS: ICM: C09K007-00. ICS: E21B043-22. APPLICATION: CN 2010-23613 25 Feb 2004. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Thermally stable viscosity-reducing agents for viscous crude petroleum are pentamethylalkyltrimethylenediammonium dichlorides, with general structure [R-N(CH3)2-CH2CH2CH2-N(CH3)3]2+.2Cl- (R = C12-, C16-, and C18-alkyl). The viscosity-reducing agents are synthesized by: (1) reaction of the amine, R-NH2, with acrylonitrile at 30-60° for 4-8 h to obtain the N-alkyl-b-aminopropionitrile, (2) hydrogenating the product from step (1) to obtain the corresponding N-alkyl-1,3-propylenediamine, and (3) exhaustive quaternization with CH3Cl at 80-90° and 0.49-0.In this study，4763-40-0 is also used.59 MPa for 2-6 h. The product is obtained as a 25-30 wt.% aq. soln. ..
