20110009662 | PROCESS FOR PRODUCING PHOSPHORUS-CONTAINING DEHYDROAMINO ACID - A process for efficiently producing through a small number of steps an N-substituted 2-amino-4-(substituted-oxymethylphosphinyl)-2-butenoic ester which is an intermediate for herbicide L-AMPB. The process comprises reacting a compound represented by the following formula (1): (where R | 01-13-2011 |
20110015428 | Process for Producing Alpha-Fluoro-Beta-Amino Acids - By reacting a β-hydroxy-α-amino acid with sulfuryl fluoride (SO | 01-20-2011 |
20140046090 | PROCESS FOR CONTINOUS FLOW SYNTHESIS OF beta-AMINO CROTONATE - Beta aminocrotonates are important intermediates for the synthesis of Ca channel blockers. The processes available in the art are batch processes with yields about 85%. There are no continuous processes available for the synthesis of such compounds. This gap in the art is addressed by the invention by disclosing a continuous process resulting in high yields of beta amino crotonates. | 02-13-2014 |
20140350291 | PROCESS FOR RECOVERING NOBLE PRODUCTS IN A PROCESS FOR PRODUCING DIALKYLAMINOALKYL (METH) ACRYLATES - The invention relates to a process for recovery of noble products from heavy (meth)acrylic fractions generated during production of (meth)acrylic esters by transesterification, the heavy fractions comprising at least noble products and Michael adducts, the process comprising the steps of: (i) adding at least one antifouling agent and optionally a viscosity-reducing compound to the heavy fractions; (ii) submitting the mixture to temperature and distillation conditions sufficient to crack the Michael adducts into their components; and (iii) recovering the noble products in the form of a stream of distillate, and of a final residue that is sufficiently fluid to be transported by pump. | 11-27-2014 |
