Formic Acid

Introduction

The industrial production of formic acid via the synthesis of methyl formate from carbon monoxide (CO) and methanol (CH₃OH), followed by hydrolysis, is a process that has gained attention for its efficiency and sustainability. Here's an overview of the technology involved:

● Carbon monoxide and methanol are reacted under high pressure in the presence of a suitable catalyst to produce methyl formate.

● The methyl formate is then hydrolyzed with water to yield formic acid and regenerate methanol, which can be recycled back into the process.

Technical Features

High Efficiency: The direct carbonylation of methanol to methyl formate is a well-established and relatively high-yield process.

Renewable Feedstock: Methanol can be produced from renewable sources like biomass or via CO₂ utilization.

Recycling of Methanol: The hydrolysis step regenerates methanol, which can be recirculated, reducing material waste and improving overall process sustainability.
