Problems solved by technology

[0004] Although tea saponin is a kind of natural surfactant, in real life, tea saponin cleaning agents have not been effectively applied, and a large part of the reason is due to the influence of some properties of tea saponin, such as its Strong foam performance, not easy to rinse

Embodiment 1

[0022] Embodiment 1: the synthesis of tea saponin monoethanolamine laurate

[0023] Add 100 grams of tea saponin into the reaction kettle, add 500 milliliters of N,N,-dimethylformamide and stir to dissolve, add 5 grams of monoethanolamine and 1 gram of catalyst sodium methoxide, heat up to 120 ° C for 12 hours, and detect by TLC After the reaction was complete, the reaction solution was concentrated to remove most of the solvent, and after cooling, it was added to 300 milliliters of petroleum ether to precipitate a solid, which was filtered and dried to obtain 102 grams of tea saponin monoethanolamine yellow powder.

[0024] Dissolve 100 grams of the obtained tea saponin monoethanolamine in 500 milliliters of N, N,-dimethylformamide, add 18 g of lauroyl chloride and 26 g of anhydrous sodium bicarbonate, stir and react at room temperature for 10 to 12 hours, after the reaction , add 300 milliliters of water to dilute, use 100 milliliters of sherwood oil: ethyl acetate (volume r...

Embodiment 2

[0026] The preparation method of the multi-purpose cleaning agent is: according to the mass ratio, first add 900-1000 grams of water, under stirring, add propylene glycol butyl ether and sodium cumene sulfonate according to the amount set by each formula in Table 1, and heat up to 50°C , then add tea saponin monoethanolamine laurate, and then add fatty alcohol polyoxyethylene ether, sodium silicate and potassium sorbate at a constant temperature, after stirring evenly, finally add water until the total mass is 2000 grams; obtain formula 1, Recipe 2 and Recipe 3.

Embodiment 3

[0034] According to the method of determination of detergency in Appendix A of QB / T 4532-2013, the detergency was tested. The cleaning agent of each formula was diluted to 1% with water, and three groups of experiments were carried out in parallel, and the average value was taken as the detergency. 1. The detergency of formula 2, formula 3, control group 1, control group 2 and control group 3 is as follows in Table 3:

[0035] table 3:

[0036] Recipe 1 Recipe 2 Recipe 3 Control group 1 Control group 2 Control group 3 Detergency 91％ 97％ 94％ 82％ 85％ 83％

[0037] From the above experimental data, it can be seen that the detergency of the formula containing tea saponin monoethanolamine laurate has been greatly enhanced compared with other control groups containing tea saponin with the same composition ratio. The non-polar laurate alkyl chain is introduced into the structure of tea saponin, which makes tea saponin monoethanolamine laurate, comp...

Abstract

The invention provides a multipurpose cleaning agent containing tea saponin monoethanolamine laurate and a preparation method of the multipurpose cleaning agent. The multipurpose cleaning agent is prepared from the following components in parts by mass: 1-3 parts of tea saponin monoethanolamine laurate, 5-10 parts of fatty alcohol-polyoxyethylene ether, 1-3 parts of sodium cumenesulfonate, 1-2 parts of sodium silicate, 0.5-1 part of potassium sorbate, 1-2 parts of sodium bicarbonate, 1-2 parts of propanediol butyl ether and the balance water, wherein the water is supplemented to the sum being100 parts. The multipurpose cleaning agent is weakly alkaline, has mild performance and cannot damage the article, has wide application range, excellent cleaning capability, and detergency over 90%, the tea saponin monoethanolamine laurate has the characteristics of biodegradability, environmental friendliness, no toxicity and no harm, and the tea saponin monoethanolamine laurate is used as a surfactant after structural modification, so that the application range of the tea saponin is expanded, the tea saponin is effectively utilized, and the utilization rate of resources is increased.

Description

technical field [0001] The invention relates to the technical field of surfactants and cleaning agents, in particular to tea saponin modified surfactants and multipurpose cleaning agents, in particular to a multipurpose cleaning agent containing tea saponin monoethanolamine laurate and its preparation method . Background technique [0002] Tea saponin, also known as tea saponin, is a kind of glycoside compound extracted from tea tree seeds (tea seeds, tea seeds). It is a natural surfactant with good performance. It can be widely used in light industry, chemical industry, Pesticides, feed, breeding, textiles, oil extraction, mining, building materials and highway construction and other fields. [0003] It has been proved by research that the HLB value of tea saponin is about 16, which can significantly reduce surface tension, has good detergency and wetting ability, and has strong foaming ability and foam stabilizing performance, and is easy to biodegrade. A class of green ...
