What happens when formaldehyde reacts with HCl?

Chloromethylation of thiols can be effected with concentrated HCl and formaldehyde: ArSH + CH2O + HCl → ArSCH2Cl + H2O. This reaction is employed in the chloromethylation of styrene in the production of ion-exchange resins and Merrifield resins.

Does formaldehyde react with acids?

It is shown that formaldehyde undergoes an acid catalyzed Cannizarro reaction in an acetic-sulphuric acid medium as well as in an aqueous solution of sulphuric acid. In an acetic-sulphuric add medium the reaction slows down when the sulphuric acid content is increased above a certain maximum.

What can formaldehyde react with?

Formaldehyde and acetaldehyde react in the presence of calcium hydroxide to give pentaerythritol, the tetranitrate of which is the explosive PETN. Large quantities of formaldehyde are used in the manufacture of urea–formaldehyde resin, phenol–formaldehyde resin, and acetal resin (polyoxymethylene).

How does formaldehyde react with DNA?

Formaldehyde reacts immediately with primary and secondary amines, thiols, hydroxyls, and amides to form methylol derivatives. It acts as an electrophile and can react with macromolecules such as DNA, RNA, and protein to form adducts and cross-links. Guanine, adenine and cytosine have amino group in their molecules.

How does formaldehyde react with proteins?

Formaldehyde is also a reactive compound which enables to bind with macromolecules in which one of them is protein. Due to the binding protein by formaldehyde causing protein damage, so it can reduce the protein function.

How formaldehyde is formed?

Formaldehyde is formed primarily by the combustion of organic materials and several natural and anthropogenic actions. Secondary formation of formaldehyde happens in the atmosphere through oxidation of natural and anthropogenic volatile organic compounds.

What is CH2O name?
