Usage

General Description

3-[(2-AMINOETHYL)AMINO]PROPANESULFONIC ACID, also known as taurine, is an organic compound that is widely distributed in animal tissues. It is a sulfur-containing amino acid that plays a crucial role in various physiological functions, including bile salt synthesis, neurological function, and cardiovascular health. Taurine is commonly found in energy drinks and supplements due to its potential benefits in enhancing exercise performance and reducing muscle fatigue. Additionally, it has antioxidant properties and may also support eye health and insulin sensitivity. Taurine is considered non-essential, as it can be synthesized in the body, but supplementation may be beneficial for individuals with certain health conditions or dietary restrictions.

Preparation method of double-terminal amino type hydrophilic chain extender

The invention discloses a preparation method of a double-terminal amino type hydrophilic chain extender. The method comprises the following steps: dissolving ethylenediamine in a solvent, dispersing, controlling the temperature of a system, dropwise adding 1, 3-propane sultone into the system, controlling the dropwise adding speed, keeping the temperature of the system, controlling the dropwise adding time to be 2-4 hours, and controlling the later aging time to be 2-5 hours; after a secondary amine value and a total amine value of a sample are monitored through central control sampling, adding alkali to carry out an acid-base reaction on a sulfonic acid part of the sample, regulating the pH to a proper range, removing a solvent existing in a system under reduced pressure, and finally adding water to adjust the solid content to a proper range, so that a double-terminal amino type hydrophilic chain extender aqueous solution can be obtained. The invention provides a preparation method of a double-terminal amino type hydrophilic chain extender similar to ethylenediamine esilate in structure and property; wherein the ring-opening reaction and selectivity of 1,3-propane sultone are utilized, and selective synthesis is carried out in an aqueous solution; the synthesis process is simple, a large number of organic solvents are not needed, a complicated post-treatment process is not needed, the preparation method is green and environment-friendly, and the industrialization degree is high.
