The sum of the squared differences between calculated and measures pressures is minimized as a function of model parameters. This method, often called Barker s method (Barker, 1953), ignores information contained in vapor-phase mole fraction measurements such information is normally only used for consistency tests, as discussed by Van Ness et al. (1973). Nevertheless, when high-quality experimental data are available. Barker s method often gives excellent results (Abbott and Van Ness, 1975).  [c.97]

An apparent systematic error may be due to an erroneous value of one or both of the pure-component vapor pressures as discussed by several authors (Van Ness et al., 1973 Fabries and Renon, 1975 Abbott and Van Ness, 1977). In some cases, highly inaccurate estimates of binary parameters may occur. Fabries and Renon recommend that when no pure-component vapor-pressure data are given, or if the given values appear to be of doubtful validity, then the unknown vapor pressure should be included as one of the adjustable parameters. If, after making these corrections, the residuals again display a nonrandom pattern, then it is likely that there is systematic error present in the measurements.  [c.107]

CH3 CH0H CH20H, a colourless, almost odourless liquid. It has a sweet taste, but is more acrid than ethylene glycol b.p. 187. Manufactured by heating propylene chlorohydrin with a solution of NaHCO under pressure. It closely resembles dihydroxyethane in its properties, but is less toxic. Forms mono-and di-esters and ethers. Used as an anti-freeze and in the preparation of perfumes and flavouring extracts, as a solvent and in  [c.139]

Ethanoic acid will attack most metals and can form acidic, basic and normal salts. It can, however, be handled in e.g. stainless steel equipment. About half the ethanoic acid produced is used as ethanoic anhydride for the manufacture of cellulose ethanoate. Large quantities are also used for the manufacture of vinyl ethanoate and various solvents. Because a number of manufacturing processes yield large amounts of dilute acid its recovery is a problem of considerable importance. Simple rectification is expensive and hence various other processes such as azeotropic and extractive distillation and liquid-liquid extraction are used. U.S. production 1978 1 240 000 tonnes.

Hydrolysed to efha-noic acid by boiling water. Manufactured by bubbling air through a mixture of ethanal and ethanoic acid in the presence of a catalyst or by reacting keten, derived by the cracking of ethanoic acid or propanone with ethanoic acid. It reacts with compounds containing an — OH,  [c.164]

Hofmann conversion of amides Amides react with solutions of chlorine or bromine in excess sodium hydroxide (NaOX) to give primary amines containing one carbon atom less than the original amide. The halogen first replaces one of the hydrogen atoms of the amido group to give a chloro- or bromo-amide which reacts with alkali to give an isocyanate this decomposes to give an amine and carbon dioxide. The reaction is used in the preparation of anthranilic acid. Overall  [c.205]
