Title: A process for the manufacture of n-(p-arsenosobenzyl)-glycine-amide and salts thereof
IPC: C07F9/74
Filed: 1948-10-15
Abstract: N-(p-arsenosobenzyl)-glycineamide of the formula <FORM:0633459/IV (b)/1> are prepared by reacting a compound of the general formula <FORM:0633459/IV (b)/2> wherein X represents -AsO3H2 or -AsO, with a halogenacetamide in alkaline solution, and when X represents -AsO3H2 the reaction product is treated with a reducing agent.  The above compounds may be converted to salts by treatment with an acid, or the reduction may be effected in the presence of a dilute mineral acid to form a salt.  The reduction may be effected with sulphur dioxide in the presence of an alkali metal iodide and a dilute mineral acid.  In examples: (1) and (2) N-(p-arsenosobenzyl)-glycineamide hydrochloride is prepared by reducing N-(p-arsonobenzyl)-glycineamide with sulphur dioxide and potassium iodide in the presence of dilute hydrochloric acid, and the starting material is obtained by reacting p-arsonobenzylamine and chloracetamide in aqueous sodium hydroxide; the corresponding sulphite is obtained by using dilute sulphuric acid instead of dilute hydrochloric acid; the free bases may be liberated from their salts with alkali such as sodium hydroxide; (3) N-(p-arsenosobenzyl-glycineamide is prepared by reacting p-arsenosobenzylamine and chloracetamide in aqueous sodium hydroxide and is isolated from the reaction mixture in the form of its hydrochloride.

Filed: 1956-09-13
Abstract: A solution of pH 3.0-5.5 of a resin of the resole type prepared from an hydroxy benzene or substituted hydroxy benzene and formaldehyde is used for hardening leather.  The specified resole is prepared from one mol. of phenol and two mols. of formaldehyde and the condensation is carried so far that the viscosity of the resole at a concentration of 59 \sB 1 per cent by weight in ethyl alcohol is 200-400 centipoises at 25 DEG  C. Specified solvents are alcohols, ketones, esters, hydrocarbons, water and mixtures of these.  Specified acidifying agents are formic acid, paratoluene sulphonic acid and mixtures of these. Concentration of resole in solvent may be 60 per cent or less.  In Example (1) the resin solution is prepared by condensing one mol. of phenol with two mols. of formaldehyde in an aqueous medium, adjusting the pH to 8.5-9.0 and refluxing at 97 DEG C. for 40 minutes followed by dehydration under vacuum at below 65 DEG  C. until a sample of the resin solution resulting dissolved in industrial ethyl alcohol to a concentration of 59 \sB 1 per cent by weight yields a solution of viscosity 200-400 centipoises at 25 DEG C. This resin is then diluted with industrial ethyl alcohol to a resin concentration of 60 per cent by weight and formic acid added to give a pH of 4.5.  In Example (2) a resin prepared as in Example (1) is dissolved in industrial ethyl alcohol and the pH adjusted to 3.5 by adding a mixture of equal parts of formic acid and paratoluene sulphonic acid and the resin concentration adjusted to 30 \sB 1 per cent by weight with a viscosity of less than 10 centipoises.
