Abstract
This disclosure provides embodiments directed to compositions, methods, and processes to produce compounds having the structure: each of R1-R5 is selected from a hydroxyl group and hydrogen; and R1-R5 include at least one hydroxyl group and at least one hydrogen; and n=0-2. In particular, methods of the disclosure can include reacting a precursor, the precursor containing more oxygen (O) atoms than the compound, with a gas containing hydrogen (H2) in the presence of a catalyst.
Claims20
A method for the production of a compound, the method comprising:
- reacting a precursor, the precursor comprising a carbohydrate or a carbohydrate derivative containing a greater number of oxygen atoms than the compound, with a gas containing H2 in the presence of a catalyst, at a pressure less than about 40 bar;
- the compound comprising:
- wherein each of R1-R5 is selected from the group consisting of:
- a hydroxyl group and hydrogen;
- and wherein R1-R5 comprise at least one hydroxyl group and at least one hydrogen;
- and wherein n=0-2.
A process for converting a carbohydrate or carbohydrate derivative to a compound, the process comprising:
- adding the carbohydrate or carbohydrate derivative to a reactor containing a catalyst;
- reacting the carbohydrate or carbohydrate derivative with a gas containing hydrogen at a reaction pressure and a reaction temperature over a reaction time;
- and
- purifying a portion of the compound from a product stream,
- wherein, the reaction pressure is less than 40 bar, the reaction temperature is between about 120° C. to about 200° C., and the reactor is designed for batch reaction.
