Abstract
Official abstract text for this publication.
Disclosed is a novel catalyst for producing a methanol precursor. The use of the catalyst enables the production of a methanol precursor and methanol with high efficiency under low temperature and low pressure conditions. Also disclosed are a methanol precursor produced using the catalyst and methanol produced using the methanol precursor.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing a methanol precursor, comprising (A) mixing a catalyst with an acid solution and supplying methane gas at a pressure of 10 to 50 bar to the mixture, the catalyst being represented by Formula 1: wherein X is selected from the group consisting of Cl, Br, I and F, and R and R′ are the same as or different from each other and are each independently selected from the group consisting of a hydrogen atom, substituted or unsubstituted C 1 -C 7 alkyl groups, substituted or unsubstituted C 8 -C 30 alkyl groups, substituted or unsubstituted C 6 -C 40 aryl groups, and substituted or unsubstituted C 2 -C 30 heteroaryl groups; or Formula 2: wherein X′ is selected from the group consisting of Cl, Br, I and F, and R″ is selected from the group consisting of a hydrogen atom, substituted or unsubstituted C 1 -C 7 alkyl groups, substituted or unsubstituted C 8 -C 30 alkyl groups, substituted or unsubstituted C 6 -C 40 aryl groups, and substituted or unsubstituted C 2 -C 30 heteroaryl groups. 2. The method according to claim 1 , wherein step (A) is carried out at a temperature of 150 to 300° C. 3. A method for producing methanol, comprising (A) mixing a catalyst with an acid solution and supplying methane gas at a pressure of 10 to 50 bar to the mixture to produce a methanol precursor and (B) reacting the methanol precursor with water to produce methanol, the catalyst being represented by Formula 1: wherein X is selected from the group consisting of Cl, Br, I and F, and R and R′ are the same as or different from each other and are each independently selected from the group consisting of a hydrogen atom, substituted or unsubstituted C 1 -C 7 alkyl groups, substituted or unsubstituted C 8 -C 30 alkyl groups, substituted or unsubstituted C 6 -C 40 aryl groups, and substituted or unsubstituted C 2 -C 30 heteroaryl groups; or Formula 2: wherein X′ is selected from the group consisting of Cl, Br, I and F, and R″ is selected from the group consisting of a hydrogen atom, substituted or unsubstituted C 1 -C 7 alkyl groups, substituted or unsubstituted C 8 -C 30 alkyl groups, substituted or unsubstituted C 6 -C 40 aryl groups, and substituted or unsubstituted C 2 -C 30 heteroaryl groups. 4. The method according to claim 3 , wherein step (B) is carried out at a temperature of 25 to 100° C.
