Embodiment Construction

[0004] The present invention has determined that the optimal test condition of preparing high viscosity sodium carboxymethyl cellulose by apple pomace is: 4g cellulose, 95% ethanol is a solvent, the consumption of 50% sodium hydroxide solution is 4g, alkalization at room temperature for 30min , 3.6g of a solution composed of 80% ethanol and chloroacetic acid at a mass ratio of 1:1.5 was used as an etherification agent, the etherification temperature was 70°C, and the etherification time was 80nin. The viscosity of the obtained CMC was 27.531mpa / s.

Abstract

Sodium carboxymethyl cellulose is a cellulose ether product which currently enjoys the most attention, has a wide application range and can be conveniently used. The sodium carboxymethyl cellulose can form high-viscosity gel and solution and has properties such as adherence, thickening, flowing, emulsification and dispersion, shaping, water holding, colloid protection, film shaping, acid tolerance, salt tolerance and suspending, so the sodium carboxymethyl cellulose is widely applicable in the production of fields such as food, medicines, daily chemicals, petroleum, paper making, textiles and buildings. For a long time, the sodium carboxymethyl cellulose is prepared with cotton linter as material, so the cost is high. If apple pomace can substitute cotton to prepare the sodium carboxymethyl cellulose, the cost of the sodium carboxymethyl cellulose can be reduced. The present invention uses the apple pomace as material to prepare the high-viscosity sodium carboxymethyl cellulose, so, not only is the cost reduced, but also waste can be utilized, so that the value of the sodium carboxymethyl cellulose can be increased.

Description

Technical field: [0001] Sodium carboxymethyl cellulose is currently the most concerned cellulose ether product, which is widely used and easy to use. Sodium carboxymethyl cellulose can form high-viscosity colloids, solutions, adhesion, thickening, flow, emulsification and dispersion, shaping, water retention, protective colloid, film forming, acid resistance, salt resistance, suspension and other characteristics, so it is used in food It is widely used in production in the fields of medicine, daily chemical, petroleum, paper making, textile, construction and so on. Background technique: [0002] For a long time, sodium carboxymethyl cellulose is prepared from cotton linters, and its cost is relatively high. If apple pomace can be substituted for cotton to make sodium carboxymethyl cellulose, the cost of sodium carboxymethyl cellulose can be reduced. At the same time, apple pomace is the product of apple juice. If it can be used, it will not only help protect the environmen...
