摘要： The invention relates to 3-hydroxypropionic acid esters, obtained by conversion of ethylene oxide with carbon monoxide in the presence of a cobalt catalyst, wherein poly-3-hydroxypropionate is obtained; and transesterification of the poly-3-hydroxypropionate with an alcohol in the presence of a transeseterification catalyst, wherein the 3-hydroxypropionic acid esters are obtained. The transesterification catalyst is a compound of the formula MLx, wherein M stands for a metal of the 2nd, 3rd, or 4th main group or the 3rd to 8th secondary group of the periodic system of the elements, L stands for a ligand, which directly bonds to an M via a C, an O, a P, an S and/or an N atom, and x is a whole number from 2 to 6.

摘要： Provided herein are recombinant host cells having an active 3-Hydroxypropionic Acid (3-HP) pathway wherein the host cells comprise a heterologous polynucleotide encoding an aminotransferase of E.C. 2.6.1.19 and wherein the aminotransferase comprises the motif (A,C)-Xn-(GSLS)-Xn-SKA(L/l)(L/l). Also described are methods of making the host cells, and methods using the cells to produce 3-HP and derivatives of 3-HP (e.g., acrylic acid).

摘要： A method of producing an ethylenically unsaturated, typically, an α, &bgr; ethylenically unsaturated carboxylic acid or ester is described. The method comprises the steps of contacting formaldehyde, or a source of formaldehyde, with a carboxylic acid or ester in the presence of a catalyst and optionally in the presence of an alcohol. The catalyst comprises barium phosphate leaf or plate shaped/like crystals, or a source thereof. A catalyst system is also described. The catalyst system comprises a crystalline barium phosphate catalyst and optionally a catalyst support.
