Title: Improvements in and relating to the manufacture of thioketones
IPC: C07D277/84
Filed: 1943-07-12
Abstract: A thioketone is prepared by condensing a quaternary salt of a heterocyclic nitrogen base of the general formula <FORM:0585666/IV/1> wherein R is alkyl or substituted alkyl, R2 is H or alkyl, X is an anion, and either (1) a is O and Z the non-metallic atoms to complete a 5- or 6-membered ring containing the group <FORM:0585666/IV/2> wherein A and B are monovalent substituents or H, or together form a fused-on ring, or (2) a is 1 and Z is <FORM:0585666/IV/3> with an ester of a dithiocarboxylic acid.  The reaction may be effected in presence of a basic condensing agent, and the group attached to the heterocyclic nitrogen atom may be an alkyl or substituted alkyl group (e.g. b -ethoxyethyl, allyl, or benzyl). Examples illustrate the production of 1-ethyl-2-thioacetylmethylene-1 : 2-dihydroquinoline from quinaldine etho-p-toluenesulphonate and methyl dithioacetate, of 3 - ethyl - 2 - thioacetylmethylene - benzthiazoline from 2 - methylbenzthiazoline etho-p-toluenesulphonate and methyl dithioacetate, of 5 - chloro - 3 - methyl - 2 - thiopropionyl - methylenebenzthiazoline from 5-chloro-2-methylbenzthiazole metho - p - toluenesulphonate and methyl dithiopropionate, of 1-ethyl-2-thioacetylmethylene-b -naphthathiazoline from 2-methyl-b -naphthathiazole etho-p-toluenesulphonate and methyl dithioacetate, of 3-ethyl-4-phenyl-2-thioacetylmethylene - 4 - thiazoline from 2 - methyl - 4 - phenylthiazole ethiodide and methyl dithioacetate, of 3 - (n - propyl) - 2 - thioacetylmethylenebenzthiazoline from 2-methylbenzthiazole n-propiodide and methyl dithioacetate, of 1-ethyl-4-thioacetylmethylene - 1 : 4 - dihydroquinoline from lepidine ethiodide and methyl dithioacetate, of 3-ethyl-2-thioacetylmethylene-a -naphthathiazoline from 2 - methyl - a  - naphthathiazole etho - p - toluenesulphonate and methyl dithioacetate, of 3-ethyl-2-(a -(thioacetyl)-ethylidene)-benzthiazoline from 2-ethylbenzthiazole ethiodide and methyl dithioacetate, of 2 - cyclohexylthioformylmethy - lene - 3 - ethylbenzthiazoline from 2 - methylbenzthiazole etho - p - toluenesulphonate and the methyl ester of dithiocyclohexanecarboxylic acid, and of 1-phenyl-2-thioacetylmethylenebenzthiazoline from 2-methylbenzthiazole pheniodide and methyl dithioacetate.  n-Butyl dithioacetate is prepared by reacting sodium dithioacetate with n-butyl bromide.  According to the Provisional Specification, the thioketone may be prepared from a quaternary salt of a heterocyclic nitrogen base containing a R2-CH2- group (wherein R2 is H or alkyl) in the a - or g -position to the quaternary nitrogen atom. Specifications 533,425, 546,705, 551,331 and 566,010 are referred to.

Patent GB-853066-A (GB)
Title: Improvements relating to the production of ammonium pentaborate and boric oxide
Inventor: CLARK SHELDON LEWIS
IPC: C01B35/10
Filed: 1958-04-09
Abstract: <PICT:0853066/III/1> Boric oxide is produced by the thermal decomposition of ammonium pentaborate formed by reacting borax and ammonium chloride in aqueous admixture, distilling the mixture until the ammonia produced has been removed and precipitating the ammonium pentaborate.  The ammonium pentaborate may be decomposed by heating at say 600-1000 DEG C.  The mother liquor remaining after removal of the precipitated ammonium pentaborate from the mixture and containing dissolved ammonium pentaborate and sodium chloride may be mixed with at least one saturated aliphatic monohydric alcohol having from 2-4 carbon atoms, e.g. denatured alcohol, n-propyl, iso-propyl or iso-butyl alcohol either alone or admixed with at least one ester of a saturated monocarboxylic acid having from 1 to 3 carbon atoms in the molecule and a saturated aliphatic monohydric alcohol having from 1 to 3 carbon atoms in the molecule, e.g. methyl or ethyl propionate or ethyl acetate, or a mixture of such esters, in amounts up to 25% based on the weight of the free alcohol, thus precipitating the sodium chloride which is removed and subsequently recovering the alcohol and/or ester by distillation of the residual liquor.  An aqueous solution containing 5-25% weight ammonium chloride and one mole of borax for say every 2-2.2 moles of ammonium chloride, is fed into a reactor 2 by line 1 and is distilled through 3 until all the ammonia produced has been removed.  The residual solution is passed through 4 into evaporator 5 where it is further concentrated by removal of water vapour by passage of a stream of air over its surface, to produce a slurry of ammonium pentaborate which is passed to filter 8 for the salt to be separated, the mother liquor passing through line 9 into settling tank 10. Sodium chloride is precipitated from the mother liquor by addition of denatured alcohol and isolated in filter 13.  Residual mother liquor passes to still 15 where alcohol is removed and recycled to settling tank 10 by line 11, residues from still 15 passing into evaporator 5.  The ammonium pentaborate from filter 8 passes to furnace 17 to be decomposed to boric oxide which is removed at 19.
