    Abstract: Hydrogenolysis systems are provided that can include a reactor housing an Ru-comprising hydrogenolysis catalyst and wherein the contents of the reactor is maintained at a neutral or acidic pH. Reactant reservoirs within the system can include a polyhydric alcohol compound and a base, wherein a weight ratio of the base to the compound is less than 0.05. Systems also include the product reservoir comprising a hydrogenolyzed polyhydric alcohol compound and salts of organic acids, and wherein the moles of base are substantially equivalent to the moles of salts or organic acids. Processes are provided that can include an Ru-comprising catalyst within a mixture having a neutral or acidic pH. A weight ratio of the base to the compound can be between 0.01 and 0.05 during exposing.

    Abstract: Chemical production processes are provided that include exposing a reactant composition to a catalyst composition to form a product composition, with the reactant composition including a multihydric alcohol compound and the catalyst composition being effective to dehydrate at least a portion of the multihydric alcohol compound. Embodiments of the process provide that the reactant composition is exposed to the catalyst composition for less than about 0.25 seconds and/or that the catalyst is maintained at a temperature of from about 2800C to about 3200C. Processes utilizing a reactant composition including a multihydric alcohol compound and an inert compound are also provided.

    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.
