摘要:The method of preparing a silver catalyst for synthesis of formaldehyde by oxidizing methyl alcohol which consists in that a carrier is impregnated with an aqueous or an aqueous-alcohol solution containing complex ions of silver having the general formula [Ag(X) n ] + or [Ag(Y) 2 ] - , where X is ammonia, ethylenediamine, triethylenetetramine or triaminotriethylamine, Y is a thiocyanate, cyanide, acetate, or hydroxyl ion, and n is 1 or 2. The impregnated carrier is processed, at a temperature of from 10° - 100°C, with a reducing agent taken in the quantity sufficient to reduce the silver completely from said ion. The thus-prepared catalyst is dried at a temperature of from 80° to 400°C. It is recommended that the catalyst be washed with water before drying. The thus-prepared catalyst has a highly developed active surface with a small content of silver (the specific surface of the catalyst is 0.7 - 7 square meters per gram, with the metal silver content of the catalyst being from 5 - 10 per cent by weight). The catalyst is highly active and has good selectivity in the process of formaldehyde synthesis from methyl alcohol. The yield of formaldehyde with the proposed catalyst is from 75 - 80 per cent, calculating with reference to the passed methyl alcohol, with the selectivity of the process being from 89 - 95 per cent.

权利人:SEROBIOLOGIQUES LAB SA
摘要:A method for the enzymatic synthesis of sucrose ester, comprises introducing, in an adapted reactor and so as to form a reaction medium, predetermined amounts of an organic solvent, a sugar or a sugar derivative, a compound donor of acyl groups and an enzymatic catalyst, the amount of at least one constituent of the reaction mixture being deficient, in controlled addition during the reaction of additional amounts of the deficient constituent(s), and finally purifying the resulting sucrose esters at least by separating the fine enzymatic particles from the solvent.

摘要:The invention relates to a method for the synthesis of kojibiose, characterised by its simplicity and high yield, using a starting reaction mixture containing, as the main compound thereof, the trisaccharide 2-α-D-glucopyranosyl-lactose, O-β-D-galactopyranosyl-(1→4)-O-[α-D-glucopyranosyl- (1→2)]-β-D-glucopyranose, and leucrose, lactose, fructose, glucose and saccharose, said method comprising steps of fermentation, hydrolysis and purification, allowing the production of a disaccharide with high added value, such as kojibiose, in a cost-effective manner. The invention also relates to the kojibiose produced by means of the method according to the invention, and to the use of same in the production of prebiotic food compositions in order to prevent pathologies relating to the gastrointestinal system, and pharmaceutical compositions for treating viral-type diseases or for delaying the digestion of carbohydrates.

摘要:Dietary supplements for treating a neurotransmitter deficiency include one or more precursors of the deficient neurotransmitter and a cofactor for activating in vivo enzymatic synthesis of the deficient neurotransmitter. The dietary supplements can also include an appropriate neurotransmitter, such as an amino acid. When administered through the oral mucosa, increases in levels of the deficient neurotransmitters and relief from deficiency symptoms are obtained.

摘要:The invention provides important intermediate compounds for the synthesis of acidic glycolipids which are identical with the glycolipid antigens isolated from the acidic glycolipid fractions of peripheral nerve and embryonic central nervous system and preparation methods thereof. By the adoption of the present intermediate compounds, sulfation of 3-hydroxyl group of end glucuronic acid portion of the acidic glycolipid can be quite easily carried out and total synthetic yield be greatly improved.
