Polymorph Control of Sulfathiazole in Supercritical CO2

Pharmaceutical Research, 2001
Sulfathiazole was used to investigate polymorph control in liquid and supercritical CO2. Conventional techniques require a variety of solvents and techniques to produce different polymorphs. The present approach involves precipitation from an organic solution with liquid or supercritical CO2 using the SEDS process.Sulfathiazole was precipitated from ...

Effect of Supercritical CO2 on PVDF

Volume 6B: Pipeline and Riser Technology, 2014
The pre-salt fields have a high content of carbon dioxide (CO2) that can be in the supercritical state due to reservoir conditions of temperature and pressure. This high concentration of carbon dioxide has a direct impact on the strategies used in the exploration and exploitation of the reservoir, including the selection of materials and equipment used

Progress in Supercritical CO2 Dyeing

Journal of Industrial Textiles, 2001
Supercritical fluids have special properties that could lead to substantial improvements when utilized as replacements for water in wet processing of textiles. These fluids have densities and solvating powers similar to liquid solvents combined with viscosity values and diffusion coefficients like those observed for gases.

Use of supercritical CO2 in food industry

2014
Supercritical fluid extraction (SFE) is the process of separating one component (the extractant) from another (the matrix) using supercritical fluids (SCF) the extracting solvent. Carbon dioxide is the most commonly used supercritical fluid in food industry, especially being used for decaffeination.

Pulverisation of Emulsions with Supercritical CO2

2016
With the use of a carbon dioxide-assisted high pressure spraying process, it is possible to manufacture solid emulsions with or without the employment of surfactants. Depending on the process parameters, such as spray pressure, temperature, and gas-to-liquid ratio, various powder morphologies and sizes in the range of micrometers can be obtained.

Ionic Liquids and Supercritical Co2

2003
Although ionic liquids (ILs) are organic solvents, They exhibit vanishing small vapour pressures [1,2]. Negligible volatility means that the most prevalent route for escape to the atmosphere and also exposure to workers — evaporation — is absent. Low vapour pressure may also renders these solvents safer, as flash points will be much higher than for ...
