Patent GB-700604-A (GB)
Title: Improvements in or relating to the flameproofing of inflammable materials
IPC: D06M13/292
Filed: 1949-11-25
Abstract: The flameproofing process of the parent Specification is modified by coating or impregnating the material with a solution, e.g. in toluene or ethylene dichloride, or dispersion of the partially polymerized phosphoric ester, drying the material and passing it through the halogen in solution, e.g. in carbon tetrachloride or ethylene dichloride, or vapour form, then through a dilute solution of alkali and finally washing.  Alternatively the material may be coated or impregnated with the monomeric ester which is polymerized in situ and similarly after-treated.  The monomeric ester may be applied as an emulsion in an aqueous solution of polyvinyl alcohol or as a solution in benzene or acetone, which may contain a catalyst such as benzoyl peroxide. Polymerization may be effected in a nitrogen atmosphere at 90 DEG C. to a bromine number of 70, corresponding to one-third of the original unsaturation.  The partially polymerized ester (bromine number 150) may be inhibited with hydroquinone, monomer and low polymers removed by distillation in vacuo or by precipitation with excess carbon tetrachloride and the residue (bromine number 90) or precipitate used for impregnation.  The dialkene amido phosphates described in Specification 699,951 may also be used in the process.

Abstract: Unsulphonated indoles are made by heating a mineral acid or a sulphonic acid salt of an arylhydrazine containing a free o-position with respect to the hydrazine group with a ketone containing in the vicinal position to the carbonyl group a methylene or a methyl group, in an aqueous medium in solution or in suspension.  Instead of the salt of the hydrazine the free hydrazine may be used and the theoretical quantity of acid is added.  A slight excess of free acid may be present and also an indifferent solvent, e.g. alcohol or acetic acid.  They may be represented by the general formula <FORM:0409350/IV/1> in which R=an aromatic residue such benzene, naphthalene, diphenyl or carbazole residues, x=alkyl or aryl, y=hydrogen, alkyl or aryl, or x and y jointly stand for a tetramethylene chain, and in which all the nuclei may contain substituents (excepting SO3H). In examples: (1) 2 : 3-dimethyl-5-methoxyindole is made from p-methoxyphenylhydrazine hydrochloride and methylethylketone in aqueous acetic acid; (2) 2-methylnaphthindole from a -naphthylhydrazine hydrochloride and acetone; (3) 2-phenylindole from phenylhydrazine hydrochloride and acetophenone (in aqueous ethyl alcohol); (4) 1 : 2 : 3 : 4-tetrahydro-7-hydroxycarbazole from m-oxyphenylhydrazine and cyclohexanone with addition of naphthalene-1 : 5-disulphonic acid; (5) 2 : 3-phenylindole from phenylhydrazine hydrochloride and benzylphenylketone; 2 : 3 - dimethyl - 5 - phenylindole from diphenyl-4-hydrazine hydrochloride and methyethylketone; (6) 2 : 3-dimethylindole-5-carboxylic acid from 4-phenylhydrazinecarboxylic acid hydrochloride and methylethylketone; the hydrochloride of 2-hydrazino-carbazole and diethylketone yield an indole of the formula <FORM:0409350/IV/2> The hydrazines from 1-amino-8-naphthol, 1-amino - 4 - chlornaphthalene and 3 - amino - carbazole and diethylketone are also specified as starting materials. Aminophenylhydrazines are made (1) by reducing a diazotized nitroamine with stannous chloride and hydrochloric acid; (2) by nitration of the hydrazine and reduction; (3) by diazotization of the corresponding monoacetyl diamines, reduction and hydrolysis.  The Specification as open to inspection under Sect. 91 is not definitely restricted to unsulphonated compounds and refers to amino sulphophenylhydrazines.  This subject-matter does not appear in the Specification as accepted.
