Abstract
Nitrilotriacetonitrile is prepared by reacting hydrocyanic acid and formaldehyde with one or more compounds of formula HO3S.NRR1, where R and R1 which may be the same or different, are H or -SO3H, e.g. by adding formaldehyde, gaseous or as aqueous solution, to an aqueous solution of the sulphuric and hydrocyanic acids; the reactants are preferably in approximately stoichiometric proportions. The sulphonic acids may be prepared by passing sulphur trioxide into concentrated aqueous ammonia; by saturating a concentrated hydroxylamine hydrochloride solution with sulphur dioxide; or, as salts, by reacting a concentrated sodium bisulphite solution with sodium nitrite with ice cooling: nitrilosulphonic acid can be obtained from the sodium salt so prepared, and can be hydrolysed to imido sulphonic and amidosulphonic acids. Specification 496,781 is referred to.
