| uses and functions | this product is used as a catalyst for polyurethane coatings and elastomers, which can promote crosslinking of aliphatic isocyanates, shorten curing time, and is also used as a heat stabilizer for PVC plastics. this product is also an excellent wetting agent for coatings, which can be used as suspending agent, matting agent, dispersant and boat primer antifouling agent, etc. As a gelling agent in ink; Can be used as oil additive; Anti-corrosion, anti-mold agent, etc. |
| Preparation of zinc isooctanoate by precipitation method | The precipitation method uses sodium hydroxide, isooctanoate and zinc sulfate as raw materials to prepare zinc isooctanoate through saponification reaction and metathesis reaction. The first step of the precipitation method is to make sodium soap first, that is, sodium hydroxide reacts with isooctanoic acid to form sodium soap (sodium isooctanoate). The chemical equation of the reaction is as follows: RCOOH NaOH = RCOONAH2O formula: R is CH3(CH2)3CH(C2H5) After the saponification reaction is completed, zinc sulfate solution is used for replacement to generate zinc isooctanate. The chemical equation of the reaction is as follows: 2RCOONa ZnSO4 = Zn (RCOO)2 Na2SO4 formula: r is CH3(CH2)3CH (C2H5) synthesis step: add a certain amount of isooctanoic acid and sodium hydroxide solution into the reactor, stir and raise the temperature to a certain temperature for saponification reaction, then add a certain amount of mineral oil and zinc sulfate solution, and react under full stirring. After the reaction is complete, let it stand and stratify, separate the lower water phase, and then clean the upper oil layer with hot water for 2~3 times, and analyze the zinc content in the washing solution. Then the upper oil phase is dehydrated by vacuum distillation to obtain the zinc isooctanate product, and the zinc content is determined, and the yield of the corresponding zinc isooctanate is calculated. |
| toxicity and hygiene | zinc 2-ethylhexanoate has a stimulating effect on skin and mucous membranes. GB 9685-2008 stipulates that (1) the maximum amount of zinc isooctanoate is 1.0% in plastic PE and PP; PS is 0.1%; Adhesives and paper shall be used appropriately according to production requirements;(2) The specific migration amount (SML, calculated as zinc) is 25.0 mg/kg. |
| use | is mainly used as a paint drier, and it has better characteristics when used in white paint |
