APPLICATION: JP 83-50584 28 Mar 1983. PRIORITY: US 82-362954 29 Mar 1982. DOCUMENT TYPE: Patent CA Section: 37 (Plastics Manufacture and Processing) Polystyrene [9003-53-6] foams are prepd. by extruding compns. comprising styrene polymer, 0.01-0.3 wt.% nucleating agent, 0.5-5.0 wt.% water, and 0.05-0.1 mol (per 100 g styrene polymer) phys. foaming agent. Thus, a compn. consisting of polystyrene 100, butane [106-97-8] 4. 9003-53-6 and 7732-18-5 which are cas registry numbers of substances are two of reagents here.8, talc 0.2, and water 1.8 g was extruded to give a foam having d. 0.029 g/cm3 and good compressive strength. .

The mechanism of high temperature combustion of propane and butane

The mechanism of high temperature combustion of propane and butane. Warnatz, Jurgen (Phys.-Chem. Inst., Univ. Heidelberg, Heidelberg 6900, Fed. Rep. Ger.). Combust. Sci. Technol., 34(1-6), 177-200 (English) 1983. CODEN: CBSTB9. ISSN: 0010-2202. DOCUMENT TYPE: Journal CA Section: 50 (Propellants and Explosives) By combination of a mechanism describing lean and moderately rich combustion of alkanes and alkenes with a mechanism describing rich combustion and formation of soot precursors in C2H2 [74-86-2] flames, a general reaction scheme is developed for the simulation of lean and rich high-temp.There are some commonly used reagents with their cas registry numbers 74-98-6 and 74-86-2 in this article. combustion of hydrocarbons up to C4. Results of these simulations are compared to exptl. data, and some consequences of this reaction scheme are discussed with respect to future exptl. work on rich flames of C3H8 [74-98-6] and C4H10 [106-97-8]. .
