Embodiment 1

[0031] The extraction of surface active substances in fresh water hyacinth leaves comprises the following steps:

[0032] Fully crush the fresh water hyacinth leaves that have been dried indoors, weigh 100g of water hyacinth leaves in a 600ml beaker, add 500ml of 50% ethanol solution, extract at 40°C for 6 hours and filter to obtain part of the filtrate; Under leaching for 6h, another part of the filtrate was filtered. The two filtrates were combined and concentrated under vacuum rotation at 55°C to obtain 6 g of a solid viscous product.

[0033] The natural surfactant compound application test of water hyacinth comprises the following steps:

[0034] (1) Compounding of fresh water hyacinth leaf surfactant and sodium lauryl sulfate: accurately weigh 0.06g of water hyacinth leaf extract, fully dissolve in distilled water and transfer to a 100ml volumetric flask, accurately weigh 0.05g of twelve Alkyl sodium sulfate was completely dissolved in distilled water, transferred to t...

Abstract

The invention relates to an extraction method based on a waterhyacinth surface active agent substance. The extraction method comprises the following steps of: mashing waterhyacinth leaves, stems or stem leaves, adding an ethanol solution, leaching for 4-8 hours at 30-50 DEG C, filtering, repeating for 1-3 times to obtain a filtered solution, and carrying out concentration. The method is simple and convenient and is easy to implement, the operation is easy, the pollution is free, and a raw material is from a reproducible biomass resource. The natural active substance extracted by the method provided by the invention can notably reduce a surface tension effect, the natural active substance can serve as a foam suppressor and has the good foam repressing property and the defoaming property, and the natural active substance also can serve as a dispersant agent with superior performance after being compounded with a general surface active agent.

Description

technical field [0001] The invention belongs to the field of preparation of surfactants, in particular to a method for extracting surfactant substances based on water hyacinth. Background technique [0002] Since the 1930s, the world-wide output and varieties of synthetic surfactants have been increasing along with the development of petrochemical industry. About 75% of synthetic surfactants are made from non-renewable petroleum products, and are widely used in various industrial fields, and the development momentum is extremely rapid ( figure 1 ). With the emergence of the earth's energy problems, the development of the synthetic surfactant industry has been severely restricted by raw materials; in addition, some traditional synthetic surfactants with poor biodegradability and environmental compatibility not only have adverse effects on organisms, but also have harmful effects on water bodies. and soil environment are also negatively affected. Therefore, finding and prep...
