This article is devoted to development of innovative technology for obtaining

cellulose from cotton linnt and obtaining cellulose from cotton lint and on the basis of the

development of chemical industry in the Republic of Uzbekistan. The study elaborates the

optimal technological parameters for cellulose removal, analyzes its quality indicators and

physicochemical properties. He also developed technology for production of carboxymethyl

compositions, which are used as a stabilizing agent of drilling mixtures for oil and gas industry.

The research results serve to increase cost efficiency, provide the local market with import-

substituting products and create new jobs.

Keywords:

Cellulose, carboxymethyl compositions, "California" poplar, cotton linth, chemical

processing, innovative technology, oil and gas industry, drilling mixes, cost-effectiveness,

secondary raw materials, physicochemical analysis.

The chemical industry is currently intensively developing as one of the most important sectors

of the economy on a world scale. Ensuring competitiveness in the global market by increasing

the number of products, improving quality and reducing cost is one of the important tasks in

this industry. Especially cellulose and its organic materials are widely used in such industries as

chemical, medical, pharmaceutical, paint and varnish, oil and gas and construction. Therefore,

the urgent task is to improve the processes for pulp extraction from industrial waste and to

create technologies for the production of high-quality products.

Important measures are being taken to develop the chemical industry in the Republic of

Uzbekistan. In particular, the "Development Strategy of New Uzbekistan for 2022-2026" pays

special attention to the production of high value-added products based on deep processing of

local raw materials and the introduction of new technologies. Within this strategy, it is

important to obtain cellulose from local raw materials, e.g. fertilizer industry waste and

secondary resources such as cotton linte, and to develop technology for the synthesis of

carboxymethyl compounds on its basis.

The purpose of identification of optimal technological parameters for obtaining cellulose

suitable for chemical processing from the secondary raw material of the "California" variety

poplar tree with the creation of innovative technology for synthesis of cellulose, cotton

cellulose and carboxymethyl starch-based compositions. Establishment of the process of

cellulose extraction by chemical processing of the secondary raw material of the "Californian"

variety poplar.

The table shows that alkaline boiling at different temperatures was carried out, with mechanical

milling at intervals of 60 min at the first stage and alkaline processing at 1600C at the second

stage for 80 min with the participation of 40 g/l alkali solution, chosen as the optimal mode.
It has a pulp yield of 54.6%, ash content of 0.93%, α-cellulose 94.8%, and a polymerization rate

of 1050.
From Table 2, it can be observed that the water vapor absorption of samples at different specific

moistures is different, i.e., the rate of water vapor sorption of poplar cellulose is higher than

cellulose, or the hydrophility of tapinambur cellulose samples is higher compared to poplar

cellulose. From such indicators it is possible to conclude that the reactivity of celluloses

obtained from the variety "Fayz-Baraka" of the Tapinambur plant is high.

From Table 3, we can see that the relative surface and relative absorption properties of cotton

and TTCH cellulose are high compared to other cellulose samples, while the Judicial index of

poplar cellulose sample is also higher than Sud of cellulose based on varieties of Tapinambur

plant. However, the Wo and Rk ratios of celluloses obtained on the basis of the Tapinambur

plant "Fayz Baraka" are higher than those of cotton, TTCH and poplar celluloses, indicating a

capillary radius of 105-112 A0.

by physicochemical methods and the definition of their application. Implementation into

production: Implementation of the created technology on an industrial scale.

The secondary raw materials of the "California" variety poplar, cotton linth, starch and cellulose

brands obtained by chemical processing were chosen as an object for the research. Research

subjects include the process of baking in alkaline solution, synthesis of technical carboxymethyl

compositions based on the obtained cellulose and starch and their application in oil and gas

industry as stabilizing mixtures.

In the experiment, physicochemical methods such as viscosimetry, titrometry, ash

determination of samples, sorption, nabuxometry and determination of water permeability were

used. These methods played an important role in determining the qualitative indicators of

cellulose and carboxymethyl compositions and their characteristics analysis. Possibility of

extracting cellulose from California poplar: The possibility of extracting cellulose from waste

from the manufacturing industry has been investigated for the first time.

To produce carboxymethylcellulose (CMS), sodium salt of monochloroacetic acid and

cellulose are used as raw materials. In order to obtain in industry by the mechanochemical

method of CMS, cellulose in a monoapparatus is mersered (in a volume sufficient to moisten

the cellulose mass) in an 18-probe alkali solution at normal temperature, ground and separated

into fibers. Then at 35-400C a sodium salt of dry monochloroacetic acid, in a mixed state, is

gradually boiled to form CMS.
[C6H7O2(OH)3*NaOH]n+ClCH2COONa
[C6H7O2(OH)x(OCH2COONa)y]n
The level of CMS metabolism is mainly controlled by the ratio of taking of cellulose and

sodium monochloroacetate, with the exception of the concentration of water and alkali in the

alkalic cellulose.

Determination of optimal parameters: Determination of optimal parameters for cellulose

extraction processes (NaOH concentration 40 g/l, grinding time 80 min, baking time 160 min,

temperature 160°C) have been determined. A new technology was developed to synthesize

carboxymethyl compositions based on poplar, pastoral cellulose and starch. The

physicochemical properties of the resulting compositions were studied, and the sphere of their

application was determined. From the secondary raw material of "California" platform cellulose

grades with different quality parameters (yield 54.6%, α-cellulose 94.8%, polymerization rate

1050) were obtained.

Based on the resulting cellulose and starch, thermally stable carboxymethyl compositions that

stabilize drilling mixes for oil and gas industry were synthesized and put into production.

In conclusion, this study made an important contribution to the development of the chemical

industry, creating an innovative technology for the production of cellulose and carboxymethyl

compositions from local raw materials. The obtained results have significant not only scientific,

but also practical value and contribute to providing the local market with import-substituting

products, creating new jobs and increasing economic efficiency.
