Embodiment 1

[0024] The proportion of raw materials added: 50 parts of lauryl sorbitan polyoxyethylene ether, 50 parts of limonene, 0.5% of the complexing agent, and 0.5% of the natural tartrazine.

[0025] Complexing process route: in a jacketed stainless steel reactor with temperature control, the temperature is controlled at 30-80 ° C, stirred, and 50 parts of lauryl sorbitan polyoxyethylene ether, 50 parts of limonene, and a complexing agent are added in turn. It is 0.5% of the whole material, and natural tartrazine is 0.5% of the whole material; after 2 hours of complexation reaction in the reactor, the whole material is a gel, and the temperature drops to 35±2 ℃ and is discharged after passing the test. The finished product should be stored in a container.

Embodiment 2

[0027] The proportion of raw materials added: 60 parts of lauryl sorbitan polyoxyethylene ether, 40 parts of limonene, the complexing agent is 0.7% of the whole material, and the natural tartrazine is 0.5% of the whole material.

[0028] Complexing process route: in a jacketed stainless steel reactor with temperature control, the temperature is controlled at 30-80 ° C, stirred, and 20 parts of lauryl sorbitan polyoxyethylene ether, 80 parts of limonene, and a complexing agent are added in turn. It is 0.7% of the whole material, and natural tartrazine is 0.5% of the whole material; after 2 hours of complexation reaction in the reactor, the whole material is a gel, and the temperature is lowered to 35±2 ℃ and the material is discharged after passing the test. The finished product should be stored in a container.

Embodiment 3

[0030] The proportion of raw materials added: 80 parts of lauryl sorbitan polyoxyethylene ether, 20 parts of limonene, the complexing agent is 0.9% of the whole material, and the natural tartrazine is 0.5% of the whole material;

[0031] Complexing process route: in a jacketed stainless steel reactor with temperature control, the temperature is controlled at 30-80 ° C, stirred, and 30 parts of lauryl sorbitan polyoxyethylene ether, 70 parts of limonene, and a complexing agent are added in turn. It is 0.9% of the whole material, and natural tartrazine is 0.5% of the whole material; after 2 hours of complexation reaction in the reactor, the whole material is a gel, and the temperature drops to 35±2 ℃ and is discharged after passing the test. The finished product should be stored in a container.

Abstract

The invention relates to a method for preparing a lauryl sorbitan polyoxyethylene ether-limonene complex. The method comprises the step of carrying out complexation on a nonionic surfactant, i.e., lauryl sorbitan polyoxyethylene ether, which serves as a complexation carrier, and limonene in the presence of a complexing agent, so as to produce the lauryl sorbitan polyoxyethylene ether-limonene complex. According to the method, the appearance of the complex is of lemon-yellow gel, the complex is of an emulsion in water, the pH value is 5 to 6, and the active matter content is 20% to 80%. The complex mainly serves as an industrial detergent and a detergent for civilian use and can also be added into a detergent formula as an intermediate. The complex plays a very good role in removing heavy oil stains and heavy glue stains.

Description

[0001] 【Technical field】 [0002] The present invention is a preparation method of lauryl sorbitan polyoxyethylene ether limonene complex, which is characterized in that the complex carrier is a nonionic surfactant lauryl under the condition of a complexing agent. Sorbitan polyoxyethylene ether is used as a complexing carrier to complex with limonene to form lauryl sorbitan polyoxyethylene ether limonene complex. [0003] 【Background technique】 [0004] Limonene, also known as limonene and limonene, belongs to monoterpenoids, colorless oily liquid with a lemon-like fragrance, widely found in monocyclic terpenes in natural plants, and the content of crude orange peel oil can reach 60-70% ;Limonene has a variety of physiological activities and biological functions, and is widely used in medicine, food, flavors and fragrances, cosmetics, cleaning agents, and pesticide industries; physical properties of limonene, flash point: 46 ℃, melting point: -74.3 ℃, boiling point : 177°C.
