Problems solved by technology

[0009] However, although DETA itself is not AEEA and is an environmentally friendly substance, it cannot completely replace AEEA due to the yellowing of the products produced by it.

Embodiment 1

[0032] Embodiment 1. Preparation of hydroxypropyl ethylenediamine

[0033] In this example, hydroxypropyl ethylenediamine as one of the softener raw materials was prepared. Refer to the technical scheme and reactor described in the patent ZL200910032856.6 "Continuous Production of Hydroxyethylethylenediamine Production Process and Reactor". Specifically, in this example, the reaction tower of this patent is used to replace the ethylene oxide in this patent with propylene oxide, and other process conditions are basically unchanged. After synthesis and rectification, the purity obtained is above 99%. Hydroxypropylethylenediamine (AEPA).

Embodiment 2

[0034] Embodiment 2. Preparation of N-hydroxypropyldiethylenetriamine

[0035] In this example, N-hydroxypropyldiethylenetriamine (hydroxypropyldiethylenetriamine) as one of the raw materials of the softener was prepared. Using a reaction kettle, under the protection of nitrogen, under the conditions of 80-150°C and 0-0.5MPa, add propylene oxide to diethylenetriamine by continuous feeding method; the molar ratio of diethylenetriamine to propylene oxide is 1 1, the product that obtains is N-hydroxypropyldiethylenetriamine (being called for short hydroxypropyldiethylenetriamine).

Embodiment 3

[0036] Example 3. Preparation of N-hydroxyethyldiethylenetriamine and N, N'-dihydroxyethyldiethylenetriamine

[0037] In this example, N-hydroxyethyldiethylenetriamine and N,N'-dihydroxyethyldiethylenetriamine were prepared as one of the softener raw materials. Using a reaction kettle, under the protection of nitrogen, under the conditions of 80-150°C and 0-0.5MPa, add ethylene oxide to diethylenetriamine by continuous feeding method; wherein, when diethylenetriamine and ethylene oxide When the molar ratio is 1:1, the obtained product is N-hydroxyethyldiethylenetriamine; when the molar ratio of diethylenetriamine and ethylene oxide is 1:2, the obtained product is N,N'- Dihydroxyethyldiethylenetriamine.

Abstract

The invention provides an environment-friendly softening agent which is used for hand feeling finishing of fabric. The softening agent is a product obtained through the following steps: dehydrating raw materials: organic amine and fatty acid in nitrogen atmosphere with phosphorous as a catalyst at the temperature of 180-200 DEG C and then dehydrating under the vacuum condition at the temperature of 200-240 DEG C; and finally, performing quaterisation and acidification. According to the invention, the softening agent, which has good hand feeling and low yellowing performances consistent with those of a softening agent commonly used at present, can be obtained by replacing a raw material: AEEA (aminoethylethanolamine) of the softening agent commonly used at present with a series of organic amine such as hydroxy-propyl-ethylenediamine and the like under the condition that the molar ratio is not changed, so that the environment and health problems caused by AEEA can be solved.

Description

technical field [0001] The invention relates to the field of textile functional finishing agents, in particular to an environment-friendly softener 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 is mainly cationic products, generally saturated hexadecanoic acid, octadecanoic acid, and hydroxyethylethylenediamine (AEEA or Aminoethylethanolamine), diethylenetriamine, etc. react to obtain imidazoline or amide, and obtain common products in quaternization and acidification. Amines mainly focus on the use of the above two raw materials, which are relatively simple. Although there are many types of other raw materials, the quantity is not large. [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 o...
