Problems solved by technology

Although the fragrance beads currently on the market can cover up the peculiar smell through their own fragrance, they cannot solve the problem caused by the growth of microorganisms at the root, and will still endanger human health
Usually, small molecule fungicides such as benzalkonium chloride and hydroxydichlorodiphenyl ether are added to the formula of the fragrance beads to obtain the bactericidal function; however, the small molecule fungicides are easily absorbed by the clothes, and the small molecule fungicides remaining in the clothes Contact with skin can easily cause skin allergies and other health problems

Embodiment 1

[0071] (1) Add 120g of N-methyldiethanolamine and 11g of sodium methoxide sequentially into the high-temperature autoclave, stir and dissolve, then raise the temperature to 90-110°C, and vacuum for 1 hour to remove methanol. Continue to raise the temperature to 130-140°C, feed 3520g of ethylene oxide at -0.1MPa to react, control the reaction temperature at 130-150°C, and control the pressure at 0.1-0.3MPa. After the ethylene oxide reaction is completed, it is aged for 1 hour, and then degassed at -0.1MPa for 30 minutes. After the degassing is completed, cool down to 65-75°C, add 70g of sodium methoxide, stir and dissolve, degas at -0.1MPa for 90min, continue to feed 167g of methyl chloride, react at 0.1-0.3MPa for 10h, then heat up to 90-100°C , Degassing at -0.1MPa for 60min. After degassing, 28 g of acetic acid was added to neutralize to neutrality to obtain an alkylated and quaternized modified N-methyldiethanolamine polyethylene glycol ether with a number average molecula...

Embodiment 2

[0074] (1) Add 120g of N-methyldiethanolamine and 16g of sodium methoxide sequentially into the high-temperature autoclave, stir and dissolve, then raise the temperature to 90-110°C, and vacuum for 1 hour to remove methanol. Continue to raise the temperature to 130-140°C, feed 8008g of ethylene oxide at -0.1MPa to react, control the reaction temperature at 130-150°C, and control the pressure at 0.1-0.3MPa. After the ethylene oxide reaction is completed, it is aged for 1 hour, and then degassed at -0.1MPa for 30 minutes. After degassing is completed, cool down to 65-75°C, add 71g of sodium methoxide, stir to dissolve, degas at -0.1MPa for 100min, continue to feed 152g of methyl chloride, react at 0.1-0.3MPa for 13h, then heat up to 90-100°C , Degassing at -0.1MPa for 90min. After degassing, 23g of acetic acid was added to neutralize to neutrality to obtain an alkylated and quaternized modified N-methyldiethanolamine polyethylene glycol ether with a number average molecular wei...

Abstract

The invention relates to a bactericidal surfactant. The bactericidal surfactant is alkylated and quaternized modified N-methyldiethanolamine polyethylene glycol ether. The invention further relates to the fragrant bead with the sterilization function and containing the sterilization surfactant and a preparation method of the fragrant bead. The novel surfactant disclosed by the invention is terminated by alkyl, so that the novel surfactant has relatively high defoaming performance, and also has an antibacterial effect due to a quaternized structure, so that the prepared fragrant bead has good bactericidal performance.

Description

technical field [0001] The application relates to the technical field of organic chemistry and daily chemical products, in particular to a bactericidal surfactant, a bactericidal pearl containing the same and a preparation method thereof. Background technique [0002] With the development and progress of society, people's requirements for quality of life are constantly improving, and people's requirements for wearing clothes are also getting higher and higher. The traditional "shape" and "color" functions of clothing can no longer meet people's requirements for individuality and self-expression, and people's requirements for the "fragrance" of clothing are becoming more and more urgent, especially for intimate clothing. In order to increase the fragrance of the clothes, it is common to add fragrances to the washing liquid at present to obtain the fragrance of the washed clothes, but the fragrance obtained by this method is not long-lasting, and there is a problem that there ...
