properties. To obtain such a pure compound‚ the compound we want must be separated from its other natural components‚ which can be done by manipulating physical and chemical properties. Panacetin contains sucrose‚ aspirin and an unknown which can be acetanilide or phenacetin in which phenacetin was created and weighed. Introduction In this lab our basic goal was to make the sucrose‚ aspirin and unknown that are formed from pharmaceutical panacetin. In doing this lab we used NaOH and diethyl either‚ along

samples. Acid hydrolysis of Nb/Ta samples separates Indium from major matrix elements like Nb and Ta and the remaining elements do not influence the selective extraction and preconcentration of In and its subsequent determination by ICP-AES or flame AAS. The silica rich geological samples are decomposed by HF-H2SO4-HCl treatment followed by dissolution in 6M HCl before applying solvent extraction procedure. In Nb/Ta type of samples‚ Indium was separated from Nb and Ta by acid hydrolysis‚ involving fusion

Results show that the integrated first and second generation ethanol production process from sugarcane leads to better economic results when compared with the stand-alone plant‚ especially when advanced hydrolysis technologies and pentoses fermentation are included. 1.

enzyme specificity of action is related to the fact that the enzyme only catalyzes one of the possible transformations of a substrate. Invertase is beta-fructofuranosidase (EC3.2.1.26)‚ which implies that the reaction catalyzed by this enzyme is the hydrolysis of the terminal nonreducing beta-fructofuranoside residues in beta-fructofuranosides. The objective of this experiment is to investigate specificity of

These derivatives were identified through the mechanism of hydrolysis‚ alcoholysis and aminolysis reactions. Positive results were obtained and the presence of a carboxylic acid derivative in each compound was confirmed. _____________________________________________________________________________________ Introduction
