Extraction Solvent Selection in Environmental Analysis

Analytical Chemistry, 2001
A method for the prediction of a suitable solvent for the extraction of pesticides is outlined. The procedure is based on the Hildebrand solubility parameter, delta(t). The solubility parameter is broken down into three individual components, which are calculated by the addition of group contributions.

Solvent selection methodology for pharmaceutical processes: Solvent swap

Chemical Engineering Research and Design, 2016
Abstract A method for the selection of appropriate solvents for the solvent swap task in pharmaceutical processes has been developed. This solvent swap method is based on the solvent selection method of Gani et al. (2006) and considers additional selection criteria such as boiling point difference, volatility difference, VLE phase diagram analysis,

Solvent selection guide: a guide to the integration of environmental, health and safety criteria into the selection of solvents

Clean Technologies and Environmental Policy, 1999
A practical, easy to use Solvent Selection Guide has been developed to provide a concise source of selected information and guidance to chemists and engi- neers to assist with their selection of solvents. It provides a relative ranking, and is limited by design to the inherent environmental, health and safety issues, in combination with general and ...

Selectivity and solvency of mixed solvents

Chemistry and Technology of Fuels and Oils, 1973
1. A comparison has been made of the solvency of extradants on the basis of calculated values of solubility parameter. 2. A study has been made of the conditions of phase equilibrium in ternary systems consisting of benzene, n-hexane, and mixed solvent. It has been shown that the band-type binodal curve [for DEG] is converted to a closed-

Selection of a solvent for adductive crystallization

Chemical Engineering Science, 1976
Abstract A procedure for screening solvents for adductive crystallization by use of the data on the enthalpy changes on complex formation, which can be easily measured experimentally, is proposed. Two parameters chemical theory of Harris and Prausnitz has been utilized for calculations of activity coefficients and selectivity values.

Diblock copolymers in selective solvents

Physica A: Statistical Mechanics and its Applications, 1991
Abstract We review our recent work on diblock copolymers in highly selective solvents. This includes the static and kinetic properties of micelles, the thermodynamic description of a copolymer layer adsorbed on a wall and the kinetics of formation of an adsorbed layer.

Selectivity of solvent for extractive crystallisation

Chemical Engineering Science, 1971
Abstract A correlation involving solubility parameters to predict the selectivity of a solvent for extractive crystallisation has been developed. It has been found that predicted and observed values of selectivity agree well for extractive crystallisation processes.

Ozone solvatochromism in selected solvents

Journal of Molecular Liquids, 2018
Abstract The solvatochromism of the ozone Hartley band was studied in 21 different liquids divided in 16 solvents and 5 acids. In all the liquids studied, ozone shows a positive solvatochromism, i.e. a red shift or batochromic shift as function of the polarity of the solvents.
