  1)First put the catalyst in the400-450Air activation at sC6-8Hour to use, to3-Methylmethamphetamine is the raw material, after the vaporizer in the180-200Vaporization at the temperature of c, pressed with air and water vapor0.002∶0.33∶0.06Volume ratio mixing, into a column tube reactor filled with activated catalysts, in the300-350Under the condition of oxidation, the reactor is connected with the molten salt tank, the heating reaction or carries the heat released by the reaction, generates the high temperature reaction gas through the heat exchanger, enters the pounce collector, and condenses the powdery crude products of niacin, the exhaust gas enters the water washing tower, the trace niacin is absorbed, discharged by the upper part of the water wash tower.

  2)The crude product obtained by the pouncer is pressed by the coarse product of niacin: water: the active carbon weight ratio is1∶4-6∶0.05-0.08Place in the reactor and heat to85-95Water release color, thermal filtration, filter into the cooling pool crystal, the filter cooled to room temperature, centrifugation drying, water content15-20% of niacin, then dried, that is, niacin.

  Synthesis method 2

  The direct gas phase oxidation of beta-methylpyridine to improve the preparation of niacin. The water and beta-methylmethium are fed into the catalyst bed separately, and the catalyst is based on the titanium dioxide carrier, which is prepared by sulfate method, which has a high surface area and 5-50% of the content of zirconia.

  Nineteen, glycine

  Preparation Method One

  The method of producing glycine, characterized by the action of microbial enzyme, enables the hydrolysis reaction solution of glycosion in the hydrolysis reaction system, thus transforming glycosirides into glycine, accompanied by the production of ammonia, in which the hydrolysis reaction system contains at least one organic impurity compound that inhibits the microbial enzyme, the organic impurity compound has a molecular weight.95and contains at least one member of the structure of the selected argon, pyridine, amide, amino, hydroxyl and subpropyl amine, the hydrolysis reaction is performed under such conditions, where the content of organic impurity compounds inhibited by microbial enzymes in the hydrolysis reaction system is maintained during the hydrolysis reaction10Weight % or less, based on the weight of the hydrolysis reaction system.

  Preparation Method 2

  A method for preparing glycine, which includes the following steps:

  1)The mixture of hydroxyethyl solution or the mixture that produces hydroxyethyl is mixed with ammonia compounds to obtain ammonia reaction fluid;

  2)The above ammonia reaction fluid is mixed with inorganic acid to obtain acid solution;

  3)The above-mentioned acid solution is combined with lime milk and is to be moderated;

  3)After treatment of the above-mentioned medium-sum liquid, get glycine.

  Purification method

  A method of purified the crude glycine in the production process, which consists of two steps:

  1)Use 50-80% of alcohol aqueous solution wash edgygin, glycine fine,

  2)Steps1)Washing master liquid inIElectrodialysis desalting treatment, to remove ammonium chloride mother liquidIITo be used in a circulating solution of alcohol before washing,

  4)The steps will be taken2)Strong water obtained after electrodialysis desalting treatmentIIConcentrated, ammonium chloride crystals, concentrated concentrated waterIAdd the circulating sleeve in the electrodialisive fraction.

  TwentyVB6

  Production Method One

  From1One deoxygenation.D。 Su-I-ketone sugar (DTP) and4One hydroxy oneLA sulpnine (HTProduction of vitaminsB6this method, which includes makingDTP和HTWith the ability byDTP和HTSynthetic vitaminsB6The enzyme reaction system prepared by the microbial cells is in contact, and the dinucleic acid phosphoric acid is chanted in the pyridoxamine glands (NADp”), pyridoxilamine gland son – nucleochlor acid (Over() and glandular risotto-scented triphosphate ()ATPThe contact in question occurs in the presence of the present.

  Production Method 2

  A method of producing vitamin B6 includes the cultivation of microorganisms belonging to the genus root tumor bacteria that can produce vitamin B6 in the medium under aerobic conditions, and then isolated from the culture. The culture is necessary for microbial growth of absorbable carbon sources, digestable nitrogen, inorganic salts and other nutrients, the medium culture can also contain acetone acid, D-glycosine, ethanolaldehyde, glycine, 1-deoxy-D-su-su-su-ketone sugar, 4-hydroxy-L-sucnine or its mixture.
