Definitions
- the invention is subject to methods for the production of B-glucose acid.
- ⁇ -Glutic acid is distinguished by a very high chemical lability and is capable of many mucus in mild conditions.
- Conventional for households, turning into products (mutation) in the case of H is complicated by the formation of ⁇ -glucose-l-l-lactone ( The ratio of the components in the equilibrium is 60% H and 40% H-lamp at a room temperature. An increase in the temperature, as well as the presence of acid, accelerates the equilibrium of this equilibrium.
- the proposed invention is a method of producing an ⁇ -gluconic acid, which is isolated in the form of Ha-sal, (Feldman D.P., Shymans Farm Zhurnal, 1984. - ⁇ ° 11. - S. 1356-1360); , 2; 5,6-di- ⁇ -i-isopropypylidene- ⁇ -glucose, the last compound is deactivated by an acidic hydrolysis in 1, 2- ⁇ -isopropypylidene- ⁇ -glucose, 1,2- ⁇ -isopropylpilidene-flop ⁇ - glucose is produced.
- Optimal is the use of sulphate-exchanged resin, which has an exchange capacity of at least 4 mg.equiv./g. in quantities of not less than 0.5 g per 0.001 mol of salt of 1,2- ⁇ -isopropustylidene- ⁇ -gluconic acid.
- the salt it is preferable to heat the salt at a temperature of 40-95 ° ⁇ .
- a lower heating temperature significantly prolongs the hydrolysis process, and an excessively high temperature leads to a decrease in the ⁇ -glucose acid intake due to its lability.

- Heating is carried out at a temperature of 40-95 ° ⁇ .
- the sulphate is acidified and exchanged, it is washed out and the water is washed off.
- the filter contains a mixture of S-glucose and S-glucose (L-glucose acid).
- the indicated temperature for the reaction is 1–5 hours without the usual process for the preparation, the total cost of the product is received (free)
- the relationship between G and G in the product is subject to only the conditions of the thermodynamic equilibrium between them (temperature and convenience). ⁇ Singh As a result of the use of a free industrial product, an ethanol content of at least 50% is used.
