The growing interest in producing biocompatible polymers, free of any kind of toxic residues, increasingly encourages the development of researches on clean processes. The use of supercritical carbon dioxide (scCO₂), replacing organic solvents, has shown to be a green alternative to traditional polymerization processes. In order to establish better conditions for polymerization reactions using the monomer globalide, the high-pressure phase behavior of systems containing carbon dioxide and globalide were studied. The experiments were performed by static-synthetic method for systems with mass fractions of CO₂ ranging from 0.3542 to 0.9480 at temperatures of 313.15, 323.15, 333.15 and 343.15 K. Transitions of vapor-liquid type with bubble point (VLE -BP) and dew point (VLE-DP) were observed between 8.96 and 25.55 MPa. The experimental results were fit using the Peng–Robinson equation of state with the conventional quadratic mixing rule (PR-vdW2), providing a satisfactory representation of the experimental data.

生产不含任何有毒残留物的生物相容性聚合物的兴趣日益浓厚，这日益鼓励人们开展有关清洁工艺的研究。使用超临界二氧化碳（scCO ₂）代替有机溶剂已被证明是传统聚合工艺的绿色替代方案。为了为使用单体全球化剂的聚合反应建立更好的条件，研究了含有二氧化碳和全球化剂的系统的高压相行为。通过静态合成方法对质量分数为CO _2的系统进行了实验温度在313.15、323.15、333.15和343.15 K时范围从0.3542到0.9480。在8.96 MPa和25.55 MPa之间观察到汽泡类型随泡点（VLE -BP）和露点（VLE-DP）的转变。实验结果通过使用Peng-Robinson状态方程和常规二次混合规则（PR-vdW2）进行拟合，从而提供了令人满意的实验数据表示。
