제목 High pressure phase behavior of lactate esters in supercritical carbon dioxide
초록 Lactate esters are interesting chemicals which made from bio-source. Various industries, from the fine chemical industry to pharmacy, use them for the solvent, ingredient, and additive. However, Some parts of them have a difficulty of general separation process due to chemical characters of lactate esters. The problem can be solved with SCF extraction. To design and operate SCF extraction for removing lactate ester from products, high pressure phase behavior data are needed. High pressure phase behavior of methyl lactate, ethyl lactate, propyl lactate, and n-butyl lactate in CO2 is measured from 363.2 K to 323.2 K with variable volume view cell. The correlation is performed with Peng-Robinson Equation of state (PR-EOS). The critical constants and the acentric factor for PR-EOS are estimated by Constantinou /Gani method.
