Overview
Dithiomorpholine (DTDM) is an organic compound widely used as a vulcanization accelerator in the rubber industry. It belongs to the class of sulfur-containing compounds and is valued for its ability to enhance the cross-linking of rubber polymers during vulcanization. The compound is known for its stability and effectiveness in improving the mechanical properties of rubber products. DTDM is commonly employed in the production of tires, hoses, and other rubber goods where high durability and resistance to heat are required. Its chemical structure allows it to release sulfur gradually during vulcanization, leading to a more controlled and efficient curing process.
Physical and Chemical Properties
Dithiomorpholine appears as a white to light yellow crystalline powder with a molecular weight of 148.25 g/mol. It has a density of 1.32 g/cm³ and a melting point range of 124-126°C. The compound is soluble in organic solvents like acetone and benzene but only slightly soluble in water. One of the key chemical properties of DTDM is its ability to act as a sulfur donor during vulcanization. This property makes it particularly useful in rubber formulations where controlled sulfur release is desired. The compound is stable under normal storage conditions but should be protected from moisture and extreme temperatures to prevent degradation.
Main Applications
The primary application of dithiomorpholine is in the rubber industry, where it serves as a vulcanization accelerator. It is especially useful in the production of high-performance rubber products such as tires, conveyor belts, and industrial hoses. The compound's ability to provide controlled sulfur release ensures uniform curing and improved product quality. Beyond rubber vulcanization, DTDM is also used in polymer modification to enhance the thermal and mechanical properties of various synthetic materials. Its versatility and effectiveness make it a valuable additive in the manufacturing of durable and high-strength rubber and polymer products.
Safety and Storage
Dithiomorpholine should be handled with care to avoid potential health hazards. Direct contact with skin or eyes can cause irritation, and inhalation of dust should be avoided. Proper personal protective equipment, including gloves and goggles, is recommended when handling the compound. Storage conditions are critical to maintaining the stability of DTDM. It should be kept in a cool, dry, and well-ventilated area, away from sources of heat and moisture. Containers should be tightly sealed to prevent contamination and degradation. In case of spillage, the area should be cleaned promptly using appropriate safety measures.
B2B Procurement Guide
When procuring dithiomorpholine, B2B buyers should prioritize suppliers who adhere to strict quality and safety standards. Verification of the CAS number (103-34-4) is essential to ensure the authenticity of the product. Buyers should also request material safety data sheets (MSDS) and certificates of analysis (CoA) from suppliers. The reference price for DTDM typically ranges between $10 and $20 per kilogram, depending on purity and order quantity. Bulk purchases may offer cost advantages, but buyers should balance price considerations with the need for reliable and consistent product quality. Establishing long-term relationships with reputable suppliers can help ensure a steady supply of high-quality dithiomorpholine.
