  Bismaleimides (BMI) exhibit excellent heat resistance (high Tg and high resistance to thermal decomposition) compared to epoxy resins and phenolic resins, and therefore, in recent years, more attention is paid to bismaleimides as a resin material for the next-generation devices represented by SiC power semiconductors, in addition to the investigation on the use of bismaleimides for electronic material applications. As such, conventional BMI's are known as highly heat-resistant resins; however, there is a demand for a resin having higher heat resistance for advanced material applications and the like. Thus, an object of the invention is to provide a novel maleimide compound having superior heat resistance. Disclosed is a substituted or unsubstituted allyl group-containing maleimide compound having a structure with three or more benzene rings, having one or more groups each having a substituted or unsubstituted allyl group, and having one or more maleimide groups.

  This invention relates to compositions and methods for fluid hydrocarbon product, and more specifically, to compositions and methods for fluid hydrocarbon product via catalytic pyrolysis. Some embodiments relate to methods for the production of specific aromatic products (e.g., benzene, toluene, naphthalene, xylene, etc.) via catalytic pyrolysis. Some such methods may involve the use of a composition comprising a mixture of a solid hydrocarbonaceous material and a heterogeneous pyrolytic catalyst component. In some embodiments, the mixture may be pyrolyzed at high temperatures (e.g., between 500° C. and 1000° C.). The pyrolysis may be conducted for an amount of time at least partially sufficient for production of discrete, identifiable biofuel compounds. Some embodiments involve heating the mixture of catalyst and hydrocarbonaceous material at high rates (e.g., from about 50° C. per second to about 1000° C. per second). The methods described herein may also involve the use of specialized catalysts. For example, in some cases, zeolite catalysts may be used; optionally, the catalysts used herein may have high silica to alumina molar ratios. In some instances, the composition fed to the pyrolysis reactor may have a relatively high catalyst to hydrocarbonaceous material mass ratio (e.g., from about 5:1 to about 20:1).

  这项发明涉及液体烃产品的组合物和方法，更具体地说，涉及通过催化裂解制备液体烃产品的组合物和方法。一些实施例涉及通过催化裂解生产特定芳香产品（例如苯、甲苯、萘、二甲苯等）的方法。一些这样的方法可能涉及使用包括固体烃质材料和异质裂解催化剂组分的组合物。在一些实施例中，该混合物可能在高温下（例如在500°C至1000°C之间）进行裂解。裂解可能进行一段至少部分足够生产离散、可识别的生物燃料化合物的时间。一些实施例涉及以较高速率加热催化剂和烃质材料的混合物（例如每秒约50°C至每秒约1000°C）。本文描述的方法还可能涉及使用专门的催化剂。例如，在某些情况下，可能使用沸石催化剂；可选地，本文使用的催化剂可能具有高硅铝比。在某些情况下，供给到裂解反应器的组合物可能具有相对较高的催化剂与烃质材料的质量比（例如从约5:1到约20:1）。
