    摘要： Polythiourethane polymer compositions, methods of making the polythiourethane polymer compositions, and methods of using the polythiourethane polymer compositions are provided. The polythiourethane can be produced by contacting a thiol ester composition and an isocyanate to produce a mixture and then heating the mixture to produce the polythiourethane polymer. In some embodiments, the thiol ester compositions include thiol esters, hydroxy thiol esters, and cross-linked thiol esters.

    摘要： Removing impurities from a heptane stream by contacting the heptane stream with an acidic catalyst, wherein the contacting reduces a concentration of one or more close boiling impurities, one or more olefins, or both. The impurities are isomerized via contact with the acidic catalyst into species that possess lower octane levels or that do not possess boiling points as near to the boiling point of n-heptane, which promotes separation of the impurities via distillation. Close boiling impurities may include such compounds as cis-1,2-dimethylcyclopentane and methylcyclohexane or may be compounds having boiling points at a standard pressure of 760 Torr in the range of about 96.5 to about 100.5 degrees Celsius including such compounds as cis-1,2-dimethylcyclopentane and methylcyclohexane. The concentration of cis-1,2-dimethylcyclopentane and methylcyclohexane may be reduced by at least about 25 and 10 percent by weight, respectively. The concentration of olefins, as measured by the Bromine Index, may be reduced by at least about 25 percent by weight.

    摘要翻译： 通过使庚烷料流与酸性催化剂接触，从庚烷物流中除去杂质，其中接触降低了一种或多种近沸点杂质，一种或多种烯烃或两者的浓度。 通过与酸性催化剂接触将杂质异构化为具有较低辛烷值或不具有接近正庚烷沸点的沸点的物质，这促进通过蒸馏分离杂质。 接近沸腾的杂质可以包括诸如顺式-1,2-二甲基环戊烷和甲基环己烷的化合物，或者可以是在约96.5至约100.5摄氏度的标准压力为760托的沸点的化合物，包括顺式-1， 2-二甲基环戊烷和甲基环己烷。 顺式-1,2-二甲基环戊烷和甲基环己烷的浓度可以分别降低至少约25重量％和10重量％。 通过溴指数测量的烯烃浓度可以降低至少约25重量％。
