    Abstract: 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.

    Abstract: The invention includes methods of producing dianhydrosugars. A polyol is reacted in the presence of a first catalyst to form a monocyclic sugar. The monocyclic sugar is transferred to a second reactor where it is converted to a dianhydrosugar alcohol in the presence of a second catalyst. The invention includes a process of forming isosorbide. An initial reaction is conducted at a first temperature in the presence of a solid acid catalyst. The initial reaction involves reacting sorbitol to produce 1,4-sorbitan, 3,6-sorbitan, 2,5-mannitan and 2,5-iditan. Utilizing a second temperature, the 1,4-sorbitan and 3,6-sorbitan are converted to isosorbide. The invention includes a method of purifying isosorbide from a mixture containing isosorbide and at least one additional component. A first distillation removes a first portion of the isosorbide from the mixture. A second distillation is then conducted at a higher temperature to remove a second portion of isosorbide from the mixture.
