Problems solved by technology

The main disadvantage of this method is that ① this method must go through pretreatment steps such as strain fermentation, which requires high production conditions and harsh operating conditions
And consume a lot of water in the process
②The large investment of simulated moving bed leads to high production cost and lack of market competitiveness

Embodiment 1

[0022] A method for processing xylose mother liquor, its concrete steps are as follows:

[0023] (1) Preparation of Xylose Dilute Purification Solution

[0024] With the discarded xylose mother liquor in the xylose production as raw material, use pure water as solvent, according to the quality (g) of xylose mother liquor: the volume (mL) ratio of pure water solvent is the ratio of 1: 2, in pure water solvent Add the xylose mother liquor, stir and mix evenly, put the solution in a vacuum filter, carry out vacuum filtration, and collect the filtrate and filter residue respectively. The collected filter residue is used for other purposes; the collected filtrate is the xylose diluted purification solution.

[0025] (2) Preparation of Xylose Mother Liquor-C 12-14 Crude Acyl Hydroxypropyl Ether

[0026] After step (1) is completed, commercially available C 12-14 Glycidyl ether is a raw material, and the volume (mL) of the filtrate (i.e. xylose dilution and purification solution)...

Embodiment 2

[0030] A method for processing xylose mother liquor, with embodiment 1, wherein:

[0031]In the (1) step, the mass (g) of xylose mother liquor: the volume (mL) ratio of pure water solvent is the ratio of 1:5.

[0032] In the (2) step, the filtrate volume (mL) collected in the (1) step: commercially available C 12-14 The glycidyl ether volume (mL) ratio is 1:3, the pH of the reaction solution is 8.2, the reaction temperature is 80° C., the rotational speed is 140 rpm, and the reaction time is 3 hours.

[0033] In step (3), the standing time is 4 hours, the temperature of the dehydration tank is 78° C., the degree of vacuum is -0.06 MPa, the moisture content is 47%, and the total yield is 87.8%.

Embodiment 3

[0035] A method for processing xylose mother liquor, with embodiment 1, wherein:

[0036] In the (1) step, the mass (g) of xylose mother liquor: the volume (mL) ratio of pure water solvent is the ratio of 1: 10.

[0037] In the (2) step, the filtrate volume (mL) collected in the (1) step: commercially available C 12-14 The glycidyl ether volume (mL) ratio is 1:5, the pH of the reaction solution is 9.2, the reaction temperature is 93° C., the rotational speed is 180 rpm, and the reaction time is 5 hours.

[0038] In step (3), the standing time is 6 hours, the temperature of the dehydration tank is 85° C., the degree of vacuum is -0.08 MPa, the water content is 50%, and the total yield is 90.6%.

Abstract

A method for processing xylose mother solutions can prepare xylose C12-14 acyl hydroxypropyl ether surface active agents from the xylose mother solutions. The method uses waste xylose mother solutions in xylose production and C12-14 alkyl glycidyl ether sold on markets as raw materials, the xylose mother solutions are diluted and filtered, then the C12-14 alkyl glycidyl ether is added to obtain xylose C12-14 acyl hydroxyporpyl ether crude products, and the coarse products are separated and purified to achieve products. The method is simple, can be performed at normal temperature and in normal pressure, can save energy and is low in treatment cost. The xylose C12-14 acyl hydroxypropyl ether surface active agents prepared in the method are high in stability, free of effect of acid and base and good in compatibility when mixed with other surface active agent. Materials are recycled in production processes, so that yield of products reaches 90.6%. The method can be widely applied to recycling of the xylose mother solutions.

Description

technical field [0001] The invention belongs to the field of biochemical technology, in particular to processing xylose mother liquor and preparing xylose C from xylose mother liquor 12-14 Acyl hydroxypropyl ether surfactant method. Background technique [0002] Xylose is a low-calorie new functional sweetener prepared from agricultural waste corncobs, bagasse, etc. It is widely used in food, medicine, chemical and other industries, especially suitable for diabetics. main raw material. According to statistics: At present, under normal conditions, the production of 1 ton of xylose will produce 1 ton of waste xylose mother liquor. In the discarded xylose mother liquor, there are also abundant glucose, xylose, arabinose and galactose. At present, most of the discarded xylose mother liquor is discharged directly, seriously polluting the environment, and only a small amount is used to produce caramel pigment, etc., and the utilization rate is very low, which seriously affects ...
