Phase behavioral study of binary systems for the vinyl Benzoate, vinyl pivalate and vinyl octanoate with carbon dioxide at high-pressure

High-pressure phase equilibrium of the binary systems CO2 + 355-TMHA and CO2 + 335-TMCHMA

“…2) and methods employed to determine the PB of the 355-TMHA and 335-TMCHMA monomers in Sc-CO 2 are depicted in depth elsewhere. [22][23][24][25][26][27][28][29][30] A 3 V cell was employed to assess the PB that controlled the pressure maximum at 200.0 MPa. Normally, CO 2 was introduced into the 3 V cell, within AE0.002 g with the aid of high-pressure equipment.…”
