About Methyl Tin Mercaptide

Methyl tin mercaptide is a key PVC heat stabiliser known for its excellent transparency, compatibility, and weatherability. It is a clear, viscous liquid that improves the heat stability, flow performance, and resistance to scaling in PVC products. Methyl tin mercaptide is widely used in PVC films, sheets, pipes, and building materials due to its simple production process and low cost. It is non-toxic, compliant with European Union’s Restriction of Hazardous Substances Directive (RoHS) regulations, and FDA-approved for food packaging.

Properties of Methyl Tin Mercaptide

Methyl tin mercaptide is a clear, viscous liquid with a density of 1.18 g/cm cube at 20°C. It has a boiling point of 515.6°C ± 60.0°C, a flash point of 137.4°C, and a vapor pressure of 0.81 Pa at 25°C. It is soluble in organic solvents and has a water solubility of 4.51 mg/L at 20°C. The liquid is non-flammable and has a low freezing point, remaining viscous even at -20°C.

Manufacturing Process of Methyl Tin Mercaptide

The production of methyl tin mercaptide involves a multi-step process. First, metal tin is reacted with chloromethane at high temperature (210-240°C) and pressure (1.0-1.3 MPa) in the presence of an amine phase-transfer catalyst. This methylation reaction produces dimethyl tin dichloride and trimethyl tin chloride. The content of trimethyl tin chloride is then controlled to be less than 0.1% through a disproportionation reaction. Next, the dimethyl tin dichloride is reacted with isooctyl mercaptoacetate to produce the final methyl tin mercaptide product. This esterification step combines the dimethyl tin intermediate with the mercaptoacetate to yield the desired compound.

Synthesis of Methyl Tin Mercaptide

Below is the detailed process of making methyl tin mercaptide:

1. Raw Material

The primary raw materials for methyl tin mercaptide production are methyl tin trichloride (MeSnCl3) and mercaptans (RSH).

2. Reaction with Mercaptans

Methyl tin mercaptide is synthesised through the reaction of methyl tin trichloride with a mercaptan.

The general reaction is as follows: MeSnCl3 + 3 RSH → MeSn(SR)3 + 3 HCl

Where Me represents a methyl group (CH3) and R represents an alkyl or aryl group.

3. Reaction with Thioglycolic Acid

A specific example of the reaction is with thioglycolic acid (HSCH2COOH) to form methyl tin tris(thioglycolate). The reaction is: MeSnCl3 + 3 HSCH2COOH → MeSn(SCH2COOH)3 + 3 HCl

4. Purification

The crude product is purified to remove any unreacted mercaptans and by-products. This typically involves distillation or recrystallisation techniques.

Applications and Drivers of Methyl Tin Mercaptide

One of the primary applications of methyl tin mercaptide is in the production of PVC films, bottles, pipes, and window frames. Methyl tin mercaptide also improves the flow properties of PVC during processing, leading to better surface quality and reduced equipment fouling. Another important application is in food packaging and medical devices. Methyl tin mercaptide is approved by regulatory bodies like the US FDA due to its non-toxic and eco-friendly nature. This allows it to be used in the production of PVC materials that come into direct contact with food and pharmaceuticals. The key drivers behind the widespread use of methyl tin mercaptide include its simple and low-cost production process, excellent compatibility with PVC, and superior performance compared to other metal-based heat stabilisers.
