Coloration Technology, EarlyView.Abstract This paper investigated the effect of temperature and time on the dyeing of polyester and cellulose diacetate and demonstrated the benefits of supercritical carbon dioxide (SC‐CO2) dyeing. It was evident that the SC‐CO2 medium enabled effective coloration of polyester at lower temperatures, ca.

Recent insights into xerogel and aerogel mineral composites for CO 2 mineral sequestration [PDF]
, 2011 Supercritically dried composites have already been analysed and proposed as carbon dioxide sequesters. However, the economical and energetic costs of the supercritical drying process had to be re-evaluated, and were eventually found not to enhance the ...

SN1 Reactions in Supercritical Carbon Dioxide in the Presence of Alcohols: the Role of Preferential Solvation [PDF]
, 2016 Ethanol (3b) inhibits SN1 reactions of alkyl halides 1 in supercritical carbon dioxide (scCO2) and gives no ethers as products. The unexpected behaviour of alcohols 3 in the reaction of alkyl halides 1 with 1,3-dimethoxybenzene (2) in scCO2 under ...

Adsorption of Carbon Dioxide on Proteins in the Supercritical Region. [PDF]
Agricultural and Biological Chemistry, 1991 The adsorption isotherms for C02 on several proteins were measured over the wide range of pressures by the gravimetric method. The apparent amount of isothermal adsorption was a maximum at just above the critical pressure, and remained constant at higher pressures, the amount differing among casein, gelatin, gluten and ovalbumin.
