摘要： A process for producing ethanol including a combination of biochemical and synthetic conversions results in high yield ethanol production with concurrent production of high value coproducts. An acetic acid intermediate is produced from carbohydrates, such as com, using enzymatic milling and fermentation steps, followed by conversion of the acetic acid into ethanol using esterification and hydrogenation reactions. Coproducts can include corn oil, and high protein animal feed containing the biomass produced in the fermentation.

摘要： A method of performing a one-pot organic reaction including carbon monoxide as reactant without the use of an external CO gas source is described wherein a reaction mixture containing a solid or liquid CO releasing compound, a non-metal substrate and a metal catalyst is exposed to an energy source to release carbon monoxide from the CO releasing compound and wherein carbon atoms of the released carbon monoxide form a bond with the non-metal substrate compound. A method of preparing chemical libraries and a kit for organic reactions are also described.

摘要： Disclosed is a producing method for a compound of formula (II), which comprises reacting a compound of formula (I) with CO 2 , in the presence of sodium t-butoxide, in an aprotic polar solvent, thereby introducing a carboxyl group at the 2- or 4-position thereof: wherein R 1 is a substituent, with a proviso that any one of R 1 's at o- or p-position to the hydroxyl group is a hydrogen atom; n is an integer of 0 to 4. There is also disclosed a producing method of a compound of formula (IV). This production method can produce phenols or naphthols having a carboxyl group introduced at the 2- or 4-position, under a relatively moderate condition and in the manner advantageous for industrial production.
