We measured the isobaric vapor–liquid equilibrium(VLE) for the quaternary system TBA + water + propane-1,3-diol + [emim]Cl at 101.3 kPa, and found the VLE data to be well correlated with the nonrandom two-liquid model. These results show that the mixed solvent of propane-1,3-diol + [emim]Cl can increase the relative volatility of TBA to water and break the azeotropic point. We found no notable synergetic effect between them, and observed that the liquid mixed solvent of propane-1,3-diol and [emim]Cl had lower viscosity than [emim]Cl, which makes it a promising entrainer for separating the TBA + water azeotrope in industrial applications.展开更多

Currently, the institute uses advanced extraction technology, the institute also produces new soybean chips and vitamin E from soybean pulp, soybean peptides, phosphatides and oligosaccharides. 120 broilers were randomly divided into 4 groups with 6 replicates in each group and 5 chicken in each replicate. The authors studied influence on performance and body quality of broiler chicken by using soybean phosphatides to take the place of 0.5%, 1% and 1.5% corn of basal daily grain. Conclusion indicated that rates of broiler chicken weight gain were 2.1%, 4.4% and 8.7%, feed utilization rates raised 3.5%, 5.2% and 8.1%, costs reduced 2.3%, 3.5% and 5.8%, chest muscle rates improved 14.7%, 0.9% and -0.49%, belly fat rates improved 11.06%, 20.28% and 44.75% by using soybean phosphatides to take place of corn in daily grain after 42 days. More recently, the study is also involved in the research on improving the meat quality of chicken by adding extracted soybean peptide and phosphatides into feed. Furthermore, nearly 98% post-consumer waste oil with high acid value can be converted into biodiesel by using an effective supercritical methanol method.展开更多
