摘要： Identified herein are inhibitors which may be added to the boiling pot portion of a distillation apparatus prior to or during the distillation of an alkylene carbonate. The inhibitors retard the occurrence of undesirable reactions of the alkylene carbonate with itself and impurities present in the pot, and hence greatly reduce or minimize the formation of undesirable by-products which otherwise tend to reduce overall yields of alkylene carbonate recovered by the distillation process. Higher distillation temperatures at higher pressures over the prior art are possible without attendant losses of significant amounts of recovered alkylene carbonate, which confers heretofore unseen flexibility in alkylene carbonate distillation.
摘要翻译： 本文所述的是在碳酸亚烷基酯蒸馏之前或期间可以加入到蒸馏装置的沸腾锅部分的抑制剂。 抑制剂阻碍碳酸亚烃酯本身和存在于罐中的杂质的不期望的反应的发生，因此大大减少或最小化不期望的副产物的形成，否则倾向于降低由蒸馏过程回收的碳酸亚烃酯的总产率。 与现有技术相比，在较高压力下的较高蒸馏温度是可能的，而不需要大量回收的碳酸亚烃酯的损失，这在碳酸亚烷基酯蒸馏中赋予迄今未见的灵活性。

摘要： A composition useful as a paint remover. The composition may include a carbonate, a dibasic ester and a mono-ester. The composition may also contain an organic sulfur-containing compound such as dimethyl sulfoxide (DMSO), a glycol ether, a ketone, or combination thereof. The composition may be used in a process for removing paint by applying it to a painted surface. The compositions have several important attributes, including low toxicity and high efficacy in removing paint and coatings.

摘要： Propylene carbonate based cleaning compositions. The compositions comprise propylene carbonate, a glycol ether, water, and an acid activator. The compositions may optionally also comprise hydrogen peroxide. The present invention also provides for a method of removing a soil from a hard surface, wherein a cleaning composition comprising propylene carbonate, a glycol ether, water, and an acid activator is applied to the hard surface. After application of the cleaning composition, the soil is removed from the hard surface without the exertion of mechanical force.
