Reactions catalyzed by zirconium sulfophenylphosphonate

Reactions catalyzed by zirconium sulfophenylphosphonate. Fu, Xiangkai; Luo, Bikui; Lei, Qingying (Dep. Chem., Southwest-China Teach. Univ., Chongqing 630715, Peop.Some commonly used reagents like 136-60-7 and 591-68-4 are used in this experiment. Rep. China). Yingyong Huaxue, 8(5), 6-9 (Chinese) 1991. CODEN: YIHUED. DOCUMENT TYPE: Journal CA Section: 21 (General Organic Chemistry) Some org. reactions such as esterification, acetal and ketal formation, etherification and prepn. of alkenes by alcs. dehydration have been first studied using zirconium sulfophenylphosphonate(ZSPP) as catalyst. The use of ZSPP is easy and has no waste acidic liquor to drain off during reactions. The catalyst can be reused and regenerated, it is a promising solid acid catalyst. .

Alkane liquid fuels production from biomass

Alkane liquid fuels production from biomass. Levy, Peter F.; Sanderson, John E.; Ashare, Edward; De Riel, Stanton (Dynatech R/D Co., Cambridge, MA, USA). Liq. Fuel Dev., 159-88. Edited by: Wise, Donald Lee. CRC: Boca Raton, Fla. (English) 1983. CODEN: 51AKAY. DOCUMENT TYPE: Conference CA Section: 52 (Electrochemical, Radiational, and Thermal Energy Technology) Section cross-reference(s): 43, 45, 48, 60 The tech. progress as well as economic assessment of a process being developed for the prodn. of liq. hydrocarbon fuel from biomass is described. The process consists of 3 distinct steps: direct mixed-culture anaerobic fermn. of untreated biomass under conditions suppressing CH4 formation to produce aliph. org. acids; recovery and concn. of the org. acids by liq.-liq. extn.; and conversion of the acids by electrolytic oxidn. to a liq. fuel comprised primarily of n-octane [111-65-9], n-nonane [111-84-2], and n-decane [124-18-5]. The product has an energy content of 114,000 Btu/gal and may be used directly as diesel fuel or blended with petroleum feedstocks. A wide variety of biomass materials are suitable substrates for the process. These include crop grown biomass (sweet sorghum), crop residues (corn stover), and forest products (aspen). Implementing an appropriate pretreatment step can extend the process to accept an even broader array of substrates. The process has a much more favorable energy balance than do typical alc. processes. 109-52-4 and 591-68-4 are just another two chemicals used in this study. An energy balance, which includes the energy necessary to grow, harvest, transport, and process the biomass indicates that the energy output will exceed the input by more than 70%. This may be compared with EtOH prodn. from biomass which has less energy output than input. .
