Method of treating heteropolysaccharide of xanthene resin type

专利摘要:
The invention relates to the microbiological industry, to methods for processing substances, in particular heteropolysaccharides, obtained by microbiosynthesis. The purpose of the invention is to improve the performance properties of a heteropolysaccharide by using its solutions for oil substitution. An aqueous solution of a heteropolysaccharide of the xanthene resin type, predominantly produced by microorganisms of the genus XANTHOMONAS, is recommended, acidified to PH 4-6 and heated for 5-15 minutes. After this treatment, the solution of the heteropolysaccharide acquires the physicochemical properties most favorable for its use as a means for the substitution of oil. 4 tab.

专利说明:

The invention relates to the microbiological industry, in particular to methods for treating such substances as heteropolysaccharides obtained by microbiosynthesis.
The purpose of the invention is to improve the operational properties of heteropolis-. harida when using its solutions for oil substitution.
Example 1. Biopolymers heteropolysaccharides, the vital products of the bacteria Xanthomonas or Arth robacter, are characterized by the properties of thickeners and viscosity agents. The most widely heteropolysaccharides of the xanthene resin type are used in secondary and tertiary oil recovery. In this case, their aqueous solutions are used to replace oil in partially depleted cavities. However, such use of heteropolysaccharide solutions leads to a rapid clogging of the pores of the mountain formations into which they are introduced, which causes an undesirable increase in pressure and prevents the additional recovery of oil.
Thermal treatment is used to alter the viscosity and / or filterability of xanthene resin solutions.
For optimum properties. solution of heteropolysaccharide, it must be acidified to pH 4-6 and heated for 5-15 minutes at 60-) 00 ° C. As a solution of a heteropoly .. lysaccharide, it is possible to use directly the filtrate of the culture liquid enriched in the heteropolysaccharide, or to extract it beforehand.

from it heteropolysaccharide and prepare its solutions.
Take two samples of 20 ml each of the culture fluid filtrate containing 2% xanthene gum. By adding concentrated sulfuric acid, the liquid is acidified to a pH of 5.5. One portion is kept for 15 minutes at 100 ° C, and then cooled to 25 ° C. The other (control) portion is held for 15 minutes at 25 (C. For comparison, the same initial liquid is subjected to heat treatment under the same conditions, but prior to the addition of sodium hydroxide, it is alkalinized to a pH of 8.5.
The effectiveness is judged by measuring the viscosity and filterability of the solutions of the heteropolysaccharide given in Table. 1.2
Example 2: Conducted experiments with samples of the filtrate of the culture liquid of 15 liters each. Processing time 15 min. The results are shown in Table. 2.2
PRI me R 3. The original filtrate of the culture fluid contains 2% xanthene resin, pH 6.8.
When acidified to pH 5.5, sulfuric acid is used. Processed Samples were tested for flow at constant pressure. The results are shown in Table. 3
 Example 4. From the filtrate of a cultural liquid, the heteropolysaccharide is precipitated with isopropane, washed and dried. The resulting powder was dissolved in distilled water with stirring. The solutions are treated by the proposed method. For comparison, the solution is treated at a pH of 6.8. The results are shown in Table. four.
Thus, thermal treatment of heteropolysaccharide solutions under the proposed conditions allows to obtain a solution with the required physicochemical properties. With extreme mode parameters, the physicochemical properties of the solutions do not allow them to be used for oil substitution.
