Problems solved by technology

Since this kind of products need to use dangerous and highly toxic chemicals such as ethylene oxide and dimethyl sulfate, it is difficult for general production plants to have the above raw materials at the same time; in addition, the production requires high requirements for equipment, personnel and process technology Therefore, few people research and produce such products in China.

Embodiment 1

[0024] In a stainless steel reaction kettle with conditions such as heating, cooling, nitrogen protection, stirring, temperature, pressure indication (recording) and feeding, add acid value 210mgKOH / g, iodine value greater than 100GI2 / 100g refined vegetable oil fatty acid (oleic acid) 534.3 g (2.00 mole), replaced with nitrogen in vacuum, stirred, and added 103 g (1.0 mole) of diethylenetriamine under the protection of nitrogen, and the molar ratio of the two was 2:1. Slowly raise the temperature to 160°C and keep it warm for 5 hours. During this process, water is generated and escapes from the system until the acid value is less than 3mgKOH / g, and a yellow liquid amidoamine intermediate is obtained. The amidation reaction of fatty acid and diethylenetriamine needs to be dehydrated. In theory, one mole of fatty acid is dehydrated to one mole. Generally, the molar ratio of the two is about 2:1. If this ratio is exceeded, triamide is easy to form, and it is difficult to disperse ...

Embodiment 2

[0029] In Example 1, using refined tallow oil instead of vegetable oil, the molar ratio to diethylenetriamine is 1.90:1.00, the molar ratio of ethylene oxide to diethylenetriamine is 5.0:1.0, other raw materials and diethylenetriamine The mol ratio of triamine is constant, and reaction condition is constant, and solvent is changed into 1,2-propanediol, and other conditions according to example 1 can obtain bis-tallow amido ethyl polyethoxymethyl methylsulfate ammonium quaternary ammonium salt. The appearance is paste, and the content of active matter is 90%. Product requires warm water to disperse.

Abstract

The invention discloses a hydrophilic softening agent and a preparing method thereof. The hydrophilic softening agent contains 70%-90% of quaternary softening agent active matter, and 10%-30% of anhydrous low-carbon solvent with low boiling point or anhydrous water-soluble solvent with high boiling point. The softening agent is free from phosphorus and the harmful substances of alkylphenol ethoxylates, formaldehyde and the like, can be biologically degraded, has the soft, hydrophilic and anti-static functions, and is used for the after treatment of cellulose fiber and the softening arrangement of papermaking, leather and the like.

Description

technical field [0001] The invention relates to a hydrophilic softener used in textile dyeing and finishing, papermaking and leather industries and a preparation method thereof. Background technique [0002] Softeners used in textiles can generally be divided into organic silicon and non-organic silicon. The latter are mainly cationic products, which generally react with saturated hexadecanoic acid and octadecanoic acid with AEEA and diethylenetriamine. Obtain imidazoline or amide, and obtain ordinary products after quaternization and acidification. This kind of product has a good soft effect, but it is not hydrophilic. The softener with good hydrophilicity can have antistatic and moisturizing effects while being soft, and it is comfortable to wear. [0003] Replace saturated acid with unsaturated acid, according to the above process, can get the corresponding hydrophilic softener, this kind of product is sold in the market under the name of ointment or soft oil. However,...
