Formamide is an amide derived from formic acid.It is a colorless liquid which is miscible with water and has an ammonia-like odor.It is chemical feedstock for the manufacture of sulfa drugs and other pharmaceuticals, herbicides and pesticides, and in the manufacture of hydrocyanic acid.
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

The Bouveault aldehyde synthesis (also known as the Bouveault reaction) is a one-pot substitution reaction that replaces an alkyl or aryl halide with a formyl group using a N,N-disubstituted formamide. [1] [2] For primary alkyl halides this produces the homologous aldehyde one carbon longer. For aryl halides this produces the corresponding ...
Pharmaceutical manufacturing is the process of industrial-scale synthesis of pharmaceutical drugs as part of the pharmaceutical industry. The process of drug manufacturing can be broken down into a series of unit operations, such as milling, granulation, coating, tablet pressing, and others.
NMF is a specialized solvent in oil refineries. It is a precursor in specialized amidation reactions where formamide would not be suitable. These reactions can generally be categorized by the following equation: R-Lg + CH 3 NHCHO → R-NCH 3 CHO + H-Lg (where Lg is a leaving group). [1] Formothion is an insecticide prepared from N-methylformamide.
[43] [44] As well as phosphorylation, formamide has been shown to be a competent medium for the production of amino acid derivatives from their simple aldehyde and nitrile precursors, demonstrating that water is not the only solvent that this process can occur in. [45] Most notably, formamide provides a medium for the prebiotic synthesis of ...
This process, practiced commercially by BASF among other companies gives 96% selectivity toward methyl formate. The catalyst for this process is sensitive to water, which can be present in the carbon monoxide feedstock, which is commonly derived from synthesis gas. Very dry carbon monoxide is, therefore, essential. [5]
