  • Method for producing hydrolysed keratinaceous material
    Patent number: 11439160
    Abstract: The method of the invention comprises the production of highly digestible hydrolysed keratinaceous material comprising the steps of (i) partly hydrolysing keratinaceous material with heat and pressure and (ii) optionally drying the resultant partly hydrolysed material comprising at least partly insoluble material and (iii) subjecting the optionally dried partly hydrolysed keratinaceous material to a chemical hydrolysis step with acid or base to obtain a highly digestible hydrolysed material, and (iv) purifying the highly digestible material. The invention further provides highly digestible keratinaceous material with an amino acid composition reflecting the amino acid composition of the raw material, wherein the amount of de-carboxylated amino acids is less than 500 ppm. Preferably all of the highly digestible material has a molecular weight lower than 10000 dalton, and preferably more than 95 wt % of the highly digestible keratinaceous material has a molecular weight of less than 5000 dalton.

  • METHOD FOR PREPARING LAMORTRIGINE AND ITS INTERMEDIATE 2,3-DICHLOROBENZOYL CHLORIDE
    Publication number: 20090312544
    Abstract: A method for preparing 3,5-diamino-6-(2,3-dichlorophenyl)-1,2,4-triazine, commonly known as lamotrigine, is disclosed. A method of preparing the intermediate, 2,3-dichlorobenzoyl chloride, by photochlorination of 2,3-dichlorobenzotrichloride followed by hydrolysis is also disclosed. The intermediate may then be used in the preparation of lamotrigine.

  • Method for the preparation of halogenated benzonitriles
    Patent number: 7576233
    Abstract: The present invention relates to a method for preparing halogenated benzonitriles by vapor phase ammoxidation at a reaction temperature in the range of 300 to 500° C. in a fixed bed reactor using a three-component catalyst. More particularly, the method of the invention relates to a method for preparing 2,6-dichlorobenzonitrile (2,6-DCBN) from 2,6-dichlorotoluene (2,6-DCT) by vapor phase ammoxidation. The invention also relates to a three-component catalyst provided on a carrier and its use in a vapor phase ammoxidation reaction according to the invention. In addition, the invention provides a method for preparing the three-component catalyst.
