aThe first one employed a styrene-divinylbenzene copolymer (SDB) as support of the Pd catalyst that generated ethyl acetate and also acetic acid. 第一个使用了苯乙烯二乙烯基苯共聚物 (SDB) 作为引起乙酸乙酯并且乙酸Pd催化剂的支持。[translate] ...
The evaporated water, acetic acid and formic acid of the solution is then condensed and is partly re-cycled and partly subjected to recovery processes. The concentrated xylose solution in the evaporator is then passed through a second ion exchanger to remove any traces of acetic acid or formic ...
The intra- and intermolecular structures through the hydrogen bonds were partly changed. A plentiful amount of acetic acid was produced in an oxidative environment, but the yield of maleic acid was kept relatively stable. 展开 关键词: hydrothermal reaction maize straw organic acid sawdust ...
(1995)used the ViewPlate, because it is constructed with a clear bottom to enable the microscopic visualization of cell growth in each well. [3H]thymidine incorporated into theDNAof living cells was analyzed in each well by treating with 10%trichloroacetic acid(TCA) to fix the cells and ...
The increased yield of gaseous phase was ascribed to oxidation decomposition of aqueous and residue. The intra- and intermolecular structures through the hydrogen bonds were partly changed. A plentiful amount of acetic acid was produced in an oxidative environment, but the yield of maleic acid was ...
We have experimental evidence that pretreatment of aqueous solution of the isooctyl ester of 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), 2,5,2′,5′-tetrachlorobiphenyl (PCB), 2,3,7,8-tetrachlorobenzo-p-dioxin (TCDD), and pentachlorophenol (PCP) by ultraviolet (UV) ozonation in a ...
The toxicity characteristic leaching procedure (TCLP) is commonly employed leaching test and designed to study hazardous nature of the waste under the worst landfill conditions. It is a batch test, uses buffer solution with a pH of 3 or 5, made of glacial acetic acid and 1 N sodium ...
(TCLP) test and the China Ministry of Ecology and Environment Standard for Pollution Control on the Landfill Site of Municipal Solid Waste (GB 16889–2008) by Solid Waste-Extraction Procedure for Leaching Toxicity-Acetic Acid Buffer Solution Method test (HJ/T 300–2007) for safe disposal in ...
Final disposal of sludge continues to be one of the more pressing problems for the wastewater treatment industry. Present regulations for municipal sludge ... J.W. Griffith,D.H. Raymond - 《Waste Management》 被引量: 255发表: 2002年 Thermal Decomposition of Acetic and Formic Acid Catalyzed by...
2,4-DICHLOROPHENOXY ACETIC ACIDRHINE RIVERThe geometry of the warm layers of stratified streams is studied on the basis of the oneâdimensional model. Particularly, the derived equations of the dimensionless length and shape of the warm layers are expressed as function of easily measured...
