    • The invention includes methods of processing an initial di-carbonyl compound by conversion to a cyclic compound. The cyclic compound is reacted with an alkyating agent to form a derivative having an alkylated ring nitrogen. The invention encompasses a method of producing an N-alkyl product. Amonia content of a solution is adjusted to produce a ratio of ammonia to di-carboxylate compound of from about 1:1 to about 1.5:1. An alkylating agent is added and the initial compound is alkylated and cyclized. The invention includes methods of making N-methyl pyrrolidinone (NMP). Aqueous ammonia and succinate is introduced into a vessel and ammonia is adjusted to provide a ratio of ammonia to succinate of less than 2:1. A methylating agent is reacted with succinate at a temperature of from greater than 100 °C to about 400 °C to produce N-methyl succinimide which is purified and hydrogenated to form NMP.
    • 本发明包括通过转化成环状化合物来处理初始二羰基化合物的方法。 该环状化合物与烷基化剂反应形成具有烷基化环氮的衍生物。 本发明包括生产N-烷基产物的方法。 调节溶液的氨含量以产生约1:1至约1.5:1的氨与二羧酸盐化合物的比率。 加入烷基化试剂并将初始化合物烷基化并环化。 本发明包括制备N-甲基吡咯烷酮(NMP)的方法。 将氨水和琥珀酸盐引入容器中并调节氨以提供小于2:1的氨与琥珀酸盐的比例。 使甲基化剂与琥珀酸酯在大于100℃至约400℃的温度下反应以产生N-甲基琥珀酰亚胺,将其纯化并氢化以形成NMP。

    • The invention includes a method of dehydration of a sugar using a dehydration catalyst and a co-catalyst within a reactor. A sugar is introduced and H 2 is flowed through the reactor at a pressure of less than or equal to about 300 psig to convert at least some of the sugar into an anhydrosugar product. The invention includes a process for producing isosorbide. A starting material comprising sorbitol is flowed into a reactor. H 2 is counter flowed through the reactor. The starting material is exposed to a catalyst in the presence of a co- catalyst which comprises at least one metal. The exposing is conducted at a hydrogen pressure of less than or equal to 300 psig within the reactor and the hydrogen removes at least some of any water present during the exposing and inhibits formation of colored byproducts.
