Embodiment 1

[0038] The method of preparing the N-n-n-dodecyl glucamine ethanol gel of the present embodiment is as follows:

[0039] 0.05 g of N-n-dodecyl glucamine (structural formula 1) was dissolved in 2 g ethanol, heated at 110 ° C until white crystals were dissolved. Then, at 20 ° C for 12 minutes, 2.5% by weight of N-n-dodecyl glucosamine gel can be formed, and the gel formed, for example figure 1 Indicated.

[0040]

Embodiment 2

[0042] The method of preparing the N-n-n-dodecyl glucamine ethanol gel of the present embodiment is as follows:

[0043] 0.05 g of N-n-dodecyl glucamine (structural formula 2) was dissolved in 4 g ethanol, heated at 110 ° C until white crystals were dissolved. Then, at 20 ° C for 15 minutes, 1.25 wt% N-n-dodecyl glucamamine gel can be formed, and the gel formed, figure 2 Indicated.

[0044]

Embodiment 3

[0046] The method of preparing the N-positive fourtoral alkyl glucamine ethanol gel of the present embodiment is as follows:

[0047] 0.05 g of N-positive foulkyl glucamine (structural formula 3) was dissolved in 2 g ethanol, heated at 60 ° C until white crystal dissolved. Then, at 30 ° C for 2 minutes, 2.5% by weight of N-n-positive decadesyl glucosamine gel can be formed, and the formed gel is image 3 Indicated.

Abstract

The invention discloses an N-alkyl glucamine small molecule alcohol gel and a preparation method and application thereof, belonging to the field of fine chemicals. The present invention utilizes N-alkyl glucamine mixed with alcohol solution and heated until white crystals are dissolved. Then stand at 0-35°C to form N-alkyl glucamine alcohol gel. The preparation process of the small-molecule alcohol gel of the invention is simple, and the pH need not be adjusted in the preparation process, and the obtained small-molecule alcohol gel has good application performance, biocompatibility, environmental compatibility and raw material reproducibility, and is suitable for the skin. It is less irritating to mucous membranes and has a soft function on fabrics and hair. It has been widely used in the fields of daily chemicals, environmental engineering, food and biomedicine.

Description

Technical field [0001] The present invention belongs to the field of fine chemical, and is specifically related to N-alkyl glucamine small molecular alcohol gel and preparation method thereof. Background technique [0002] Glycosyl surfactants are new hotspots in the field of surfactants. By connecting a hydrophilic group or the hydrophilic group obtained in the sugar molecule, the surfactant obtained by the hydrochemical product is the lack of surface active surfactant with good surface performance while having good surface performance. Sex, safety, germial and biodegradability. As a most basic monosaccharide, glucose is a wide range of other sugars, and it is natural, renewable resources, and its derivatives have significant advantages such as safe, mild, low cost, low prolonged degradation. The glucamine-type surfactant is a continuous increase in detergent active in foreign detergent formulations in recent years. Such surfactant is a new type of surface activity of naturally ...
