Trimethyl Phosphate (TMP), a colorless transparent liquid with the CAS number 512-56-1, is a fundamental organophosphate compound with a distinct chemical profile. Understanding its properties and synthesis is key for B2B professionals seeking high-quality chemical intermediates. As a leading manufacturer in China, we utilize advanced synthesis processes to produce TMP that meets stringent quality standards.

Chemical Structure and Properties:

The molecular formula for Trimethyl Phosphate is C3H9O4P, with a molecular weight of 140.07 g/mol. The structure consists of a central phosphorus atom bonded to three methoxy groups (-OCH3) and one oxygen atom. This arrangement gives TMP its characteristic properties:

  • Appearance: Colorless transparent liquid.
  • Solubility: Readily soluble in water and common organic solvents like ether.
  • Stability: Relatively stable under normal conditions.
  • Reactivity: Acts as a mild methylating agent and can participate in various esterification and extraction processes.

These properties make TMP highly effective as a solvent, extractant, and intermediate in numerous chemical reactions.

Synthesis of Trimethyl Phosphate:

The industrial synthesis of Trimethyl Phosphate typically involves the reaction of phosphorus oxychloride (POCl3) with methanol (CH3OH) in the presence of a base, such as potassium carbonate (K2CO3). This process is carefully controlled to ensure high yield and purity. The general reaction pathway involves:

  1. Reaction of phosphorus oxychloride with methanol to form TMP and by-products.
  2. Purification steps including washing, bleaching, dehydration, and vacuum distillation to isolate high-purity TMP.

Our manufacturing facilities employ optimized synthesis routes, using high-quality raw materials like phosphorus oxychloride and methanol. We achieve an assay of ≥99% through rigorous quality control measures during each stage of production. The fixed material consumption quota for our process, for instance, is 1094 kg of phosphorus oxychloride and 686 kg of methanol per ton of TMP produced, reflecting our efficient operational standards.
