    摘要: 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.

    摘要: Oncoproteins such as Ras and RhoB are known to induce cell division in an unrestrained manner when such proteins are localized at the inner surface of a cancer cell membrane. The localization is effected by the prenylation reaction, whereby a hydrophobic group (e.g. a farnesyl group) is attached to the protein in the presence of an enzyme (e.g. farnesyl protein transferase). Deactivation of the prenylation enzyme through covalent modification can therefore ultimately result in the mitigation and/or cessation of cancer cell growth. Various prenylation inhibitors having the necessary structural groups to bond covalently, or essentially irreversibly, to the prenylation enzyme include carbonyl or thiocarbonyl compounds (or masked versions of these compounds) and alpha oxo-epoxides bonded to a hydrophobic, substrate-mimicking group. The carbonyl or thiocarbonyl compounds also contain a nucleofugal atom or group to enhance the tendency to form covalent bonds.

    摘要: The invention relates to a method for producing N,N-dimethylaminoethyl acrylate by the transesterification reaction of an alykl acrylate by N1N-dimethylaminoethanol, and more particularly relates to a method for purifying the azeotropic fraction generated during said reaction, thereby enabling the recycling thereof on the alkyl acrylate production unit. The aim of the method of the invention is in particular to remove the acetaldehyde and the dialkoxyethane contained in the azeotropic fraction, either by the direct distillation of the azeotropic fraction or by the distillation of the aqueous phase resulting from the water scrubbing of the azeotropic fraction.

    摘要: An oxybutynin and its derivatives are produced by reacting a phenylketone with a silylcyanide in the presence of a specified asymmetric catalyst to obtain a siloxynitrile, and then reacting the siloxynitrile with a reducing agent and oxidizing the resulting aldehyde, or subjecting the siloxynitrile to a hydrolysis.
