| titleOfInvention | Method for manufacturing multi functional sequestering agent |
| abstract | The present invention relates to a method for preparing a multifunctional metal ion sequestrant, comprising: (A) a sugar-base alcohol as a natural base, and a group of polyhydric alcohols and maleic anhydrides selected from mannitol, d-sorbitol, erythritol, arabitol, and xylitol. Ester reaction was carried out by molar ratio of 1: 1 ~ 1: 10 between monomers selected from group, acrylic acid and methacrylic acid to prepare Ester Monomer, the first reaction product, and selected from maleic anhydride, acrylic acid and methacrylic acid. Copolymers were prepared at a mole ratio of 10: 1 to 0.01: 1 between the monomers containing the group 1 carboxyl group and the ester reaction product, Ester Monomer, to prepare a copolymer, a secondary reaction product, wherein the reaction initiator is sodium persulfate (SPS), Using a group selected from Ammonium persulfate (APS), Potassium persulfate (KPS) and proceeds for 5 hours at 40 ~ 100 ℃, and finally to prepare a first sodium salt copolymer by adding NaOH to the secondary reaction product ; (B) Mole ratio between 1: 1 and 1:10 between Endiol and Acrylic acid, each of which has a structure in which one hydroxyl group is bonded to Glucose, an aldohexose having an aldehyde group (-CHO) on one side, or a carbon atom of a double bond. To form a second sodium salt copolymer finally by adding NaOH; (C) preparing a surfactant having vegetable oil (vegetable oil) or vegetable oil derivatives and adding ethylene oxide in a mole ratio of 1: 7 to 1: 9 to synthesize a surfactant having water solubility, salt stability and dispersibility; (D) mixing the first sodium salt copolymer, the second sodium salt copolymer, and a surfactant to complete the metal ion sequestering agent. According to the present invention, it is possible to manufacture a metal ion sequestrant with a variety of functionalities that can be used more useful in the pre-treatment, dyeing and processing processes of the textile industry, and to produce an eco-friendly metal ion sequestrant containing no nitrogen and phosphorus components It can improve the environmental pollution such as eutrophication, and can show various functions such as metal ion containment, salt stability, and dispersibility as well as excellent biodegradability, which can reduce energy in dyeing process and prevent excessive use of chemicals. Can be provided. |
