Dimethyl tin dilaurate is an organotin compound that is commonly used as a catalyst in the production of polyesters, polyamides, and polyurethanes. It is a colorless to pale yellow liquid that is soluble in most organic solvents. DIMETHYL TIN DILAURATE is known for its ability to promote the polymerization of unsaturated polyester resins and is also used as a crosslinking agent in the production of coatings and adhesives. However, it is important to note that dimethyl tin dilaurate is toxic to aquatic organisms and can cause skin and eye irritation in humans, so proper safety measures must be taken when handling this chemical.

2179-99-9 Usage

Uses

Used in Polymer Production Industry:
Dimethyl tin dilaurate is used as a catalyst for the production of polyesters, polyamides, and polyurethanes. It facilitates the polymerization process, resulting in the formation of these polymers with desired properties.
Used in Coatings and Adhesives Industry:
Dimethyl tin dilaurate is used as a crosslinking agent in the production of coatings and adhesives. Its ability to promote crosslinking enhances the durability and performance of these products.
Used in Unsaturated Polyester Resin Industry:
Dimethyl tin dilaurate is used as a promoter for the polymerization of unsaturated polyester resins. This promotes the formation of a network structure, which is essential for the final properties of the resin.

Check Digit Verification of cas no

The CAS Registry Mumber 2179-99-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,7 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2179-99:
(6*2)+(5*1)+(4*7)+(3*9)+(2*9)+(1*9)=99
99 % 10 = 9
So 2179-99-9 is a valid CAS Registry Number.

Preparation method of methyltinlaurate

-

Paragraph 0027-0030; 0035-0046; 0051-0052; 0057-0058, (2017/07/21)

A preparation method of methyltinlaurate uses a methyl tin chloride water solution, lauric acid and alkali liquor as main raw materials and is used for one-step synthesis of the methyltinlaurate. The method comprises the following steps that 1, the lauric acid and the methyl tin chloride water solution are put in a reaction kettle, the mixture is heated and stirred, and the alkali liquor is dropwise added when the temperature is up to 50-70 DEG C; 2, the temperature of a reaction system is controlled to be 50-70 DEG C, alkali liquor adding continues in a dropwise mode, and when the pH value of the mixed liquid is up to 4-7, alkali liquor adding is stopped, and standing is performed for phase splitting; 3, an organic phase is taken for washing, and then standing is performed for phase splitting; 4, reduced pressure distillation is conducted on organic matter at the temperature of 60-140 DEG C, water and other low-boiling-point impurities are removed, and then filtration is performed to obtain the methyltinlaurate. Methyl tin oxide and other durst raw materials are not related, lauric acidsaponification is avoided, waste water can be recycled, and the preparation method has the advantages that production equipment is simple, control is easy, the manufacturing cost is low and product quality is stable.
