纤维素衍生的平台化学品为大多数基于石油的聚合物提供了可行的替代品，也使新型功能材料的开发成为可能。这项工作的重点是二氢左旋糖苷酮(环素)和左旋糖苷酮的热物理和热化学研究，这两种化合物被认为是工业极性非质子溶剂的潜在绿色替代品。测定了环烯和左旋葡萄糖酮的密度、粘度、绝对蒸汽压和燃烧能。左旋葡聚糖衍生物的热力学性质在热化学计算中是可靠的，并用于计算生物质中纤维素组分的价化反应热。这些反应热有助于进一步优化和开发可持续地合成商品化学品和生物质燃料。随着这些新溶剂的使用增多，这项工作中提供的数据将有助于研究人员和工程师。
Cellulose-derived platform chemicals offer viable substitutes for most petroleum-based polymers and also enable the development of novel functional materials. In the focus of this work are thermophysical and thermochemical studies of dihydro-levoglucosenone (Cyrene) and levoglucosenone, which are considered as potential “green” replacements for industrial polar aprotic solvents. The densities, viscosities, absolute vapor pressures, and combustion energies of cyrene and levoglucosenone were measured in this work. The thermodynamic properties of levoglucosan derivatives are reliable for thermochemical calculations and used to calculate reaction enthalpies of valorization of the cellulose component of biomass. These enthalpies of reaction are useful in the further optimization and development of sustainable syntheses of commodity chemicals and fuels from biomass. The data provided in this work will aid researchers and engineers as the use of these new solvents grows.
