Abstract
The present invention is in the field of a process for producing an ester, such as a biobased ester, from an aqueous biomass comprising solution, batch wise or continuously, wherein use of raw material is limited and if possible re-used. The present invention is in the field of green technology.
Claims
1. A green process minimizing use of chemicals and energy for producing a carboxylate ester, from a renewable resource comprising the steps:
providing a water soluble carboxylate,
providing a transfer agent,
removing water, if present, and
providing a di-alkyl carbonate,
reacting the carboxylate, transfer agent and di-alkyl carbonate thereby forming a di-alkyl ester of the
carboxylate, and a carbonate, substantially in absence of water,
wherein a liquid or solid anion exchanger comprises the transfer agent, and wherein the transfer agent comprises a (bi) carbonate species.
2. A process according to claim 1, wherein the transfer agent is a positively charged transfer agent, wherein the transfer agent is supported on a solid or diluted in a suited liquid phase.
3. A process according to at least one of the preceding claims, wherein the carboxylate is produced by biotransformation, wherein a pH of the medium is from 4- 10.
4. A process according to at least one of the preceding claims, wherein the carboxylate is a mono-, di- or tri- carboxylate, and combinations thereof,
5. A process according to at least one of the preceding claims, wherein ester is a mono-, di- or tri ester.
6. A process according to at least one of the preceding claims, wherein the di-alkyl carbonate comprises an alkyl selected from the group of C1-C12, and
combinations thereof,
7. A process according to at least one of the
preceding claims, wherein the water soluble carboxylate
comprises one or more of Na+, NH4 +, K+, Mg2+, Ca2+, and combinations thereof.
8. A process according to at least one of the preceding claims, wherein the water soluble carboxylate is sorbed by an anion exchanger, thereby forming an aqueous (bi) carbonate salt, and a complex of the carboxylate and transfer agent,
wherein the (bi) carbonate salt solution is preferably recovered to be used in the production of the carboxylate.
9. A process according to claim 8, wherein the resin is dried, and thereafter the di-alkyl .carbonate is provided to the resin in order to form the ester,
wherein the carbonate is provided to the transfer agent.
10. A process according to claim 8 or 9, wherein the ester is formed at a temperature of 20-140 °C, at a pressure of 80-900 kPa.
11. A process according to at least one of the preceding claims, wherein the ester is purified.
12. A process according to at least one of the preceding claims, wherein the carboxylate is purified.
13. A process according to at least one of the preceding claims, wherein the reacting is carried out as a solid-liquid, gas-solid or liquid-liquid reaction, preferably as a solid-liquid reaction.
14. A carboxylate ester obtainable by a process according to any of claim 1-13, preferably wherein the carboxylate is produced by biotransformation.
