Embodiment 1

[0023] A preparation method of modified chlorinated paraffin, comprising the steps of:

[0024] S1. Dissolve 1 part of chlorinated paraffin in 10 parts of acetone by weight. After the chlorinated paraffin is completely dissolved, add 1 part of thiosalicylic acid and 2 parts of potassium carbonate, and react at a temperature of 90°C under nitrogen protection. After 24 hours, after the reaction is completed, pour the reactant into 10 parts of ethanol / water (the volume ratio of ethanol and water is 2:1) mixed solution, and dry in vacuum for 2 hours to obtain a transparent liquid;

[0025] S2. Dissolving the above transparent liquid in 10 parts of tetrahydrofuran, adjusting the pH value to 4 with hydrochloric acid, then pouring into 10 parts of ethanol for extraction, and drying in vacuum for 2 hours to obtain a transparent liquid thiosalicylic acid modified chlorinated paraffin product;

[0026] S3. Add 1 part of thiosalicylic acid-modified chlorinated paraffin product to 10 part...

Embodiment 2

[0028] A preparation method of modified chlorinated paraffin, comprising the steps of:

[0029] S1. Take 2 parts by weight of chlorinated paraffin and dissolve in 15 parts of acetone. After the chlorinated paraffin is completely dissolved, add 2 parts of thiosalicylic acid and 2 parts of potassium carbonate, and react at a temperature of 70°C under nitrogen protection. After 24 hours, after the reaction is completed, the reactant is poured into 15 parts by weight of ethanol / water (the volume ratio of ethanol and water is 2:1) mixed solution, and vacuum-dried for 2 hours to obtain a transparent liquid;

[0030] S2. Dissolving the above transparent liquid in 15 parts of tetrahydrofuran, adjusting the pH value to 4 with hydrochloric acid, pouring into 10 parts of ethanol for extraction, and drying in vacuum for 2 hours to obtain a transparent liquid thiosalicylic acid-modified chlorinated paraffin product;

Abstract

The invention discloses a preparation method of modified chlorinated paraffin, which comprises the following steps: dissolving chlorinated paraffin in a solvent, adding thiosalicylic acid and potassium carbonate, reacting at 50-100 DEG C under the protection of nitrogen, pouring that reactants into an ethanol solution, and performing vacuum drying to obtain a transparent liquid; dissolving the clear liquid in a solvent and adjusting the pH to 4-5, pouring into ethanol to extract, vacuum drying to obtain thiosalicylic acid modified chlorinated paraffin product; adding the chlorinated paraffin modified by thiosalicylic acid into solvent, then adding epoxy fatty acid methyl ester and N,N-dimethyl formamide, performing reflux reaction at 50-80 DEG C, pouring into ethanol to extract, vacuum drying to obtain modified chlorinated paraffin. The invention also discloses a modified chlorinated paraffin. The invention also discloses the application of a modified chlorinated paraffin in a plasticizer. The modified chlorinated paraffin prepared by the invention is environmentally friendly, has good compatibility with organic substances and good plasticizing effect, and can improve the deficiency of the traditional chlorinated paraffin.

Description

technical field [0001] The invention relates to the technical field of modified chlorinated paraffin, in particular to a modified chlorinated paraffin and its preparation method and application. Background technique [0002] Chlorinated paraffin is a traditional auxiliary plasticizer for polyvinyl chloride, but its plasticizing effect is poor, and it is easy to remove HCl under the action of light or heat during use, resulting in a decrease in its own polarity, resulting in a reaction with polyvinyl chloride. The resin compatibility gradually decreases, and the products gradually harden. Therefore, the application of chlorinated paraffin in the field of plasticizers is limited. The preparation of modified chlorinated paraffin plasticizers with good plasticizing effects will broaden its application fields and increase product additions. value is significant. [0003] CN 201810719663.7 discloses a bisphenol-A modified heat-resistant chlorinated paraffin and its preparation me...
