Title: Novel naphthaquinols and a process for the manufacture thereof
Inventor: MARRIAN DENIS HAIGH
IPC: C07F9/12
Filed: 1961-02-13
Abstract: The tetrasodium salt of 2-methyl-6-iodo naphthaquinol-(1,4)-di(phosphoric) acid is prepared as follows:-Sodium 2-methylnaphthalene-(6) sulphonate is treated with POCl3 to give the corresponding sulphonyl chloride which is then reduced with zinc and water to the corresponding sulphinate.  To this compound in boiling water mercuric chloride and hexanol are added, and the resulting solid treated with iodine in ethanol to give 2-methyl-6-iodo-naphthalene.  This compound is phosphorylated by known methods and the phosphorylation residue hydrolysed with lithium hydroxide.  The lithium salt obtained is dissolved in water, passed through a column of an ion exchange resin in its acid form, the column is then washed with water and the eluate neutralised with NaOH and evaporated in vacuo under nitrogen to give the desired sodium salt which is further purified by treating a methanol solution with charcoal, adding ethanol and refluxing to give the pure compound. The tetrasodium salt of 2-methyl 5:6-7-tribromo-naphthaquinol (1,4)di(phosphoric acid) is obtained by treating 2-methyl-6-aminonaphthalene hydrochloride with tosyl chloride in pyridine solution to give the tosyl derivative which is treated with Br2 in acetic acid to give 2-methyl-5,7-dibromo-6-tosylamino-naphthalene.  This is hydrolysed with H2SO4 to give the amine which is (a) diazotised and treated with Cu2Br2 to give 2-methyl-5,6,7-tribromo-naphthalene or (b) diazotised and treated with bromine in HBr to give the diazo per bromide, which is refluxed with chloroform and acetic anhydride to give the same product as method (a).  The product is converted to the quinone with Na2Cr2O7 and sulphuric acid, and the quinone is treated with NaHSO3 and H2SO3 solution to give the quinol which is converted to the desired salt by a method similar to that used for the preparation of the iodo compound.  The tetrasodium salt of 2-methyl-5,6-dibromonaphthaquinol (1,4)-di(phosphoric acid) is obtained from 2-methyl-6-amino naphthalene hydrochloride by dissolving this in acetic acid and brominating by passing a stream of air through bromine and into the solution.  The product is 2-methyl-5-bromo-6-amino naphthalene which is then treated by the stages indicated for the amine intermediate of the tribromo compound to give the desired salt.  Salts containing two or more halogen atoms and the 5,6,7 tribromo compound are claimed per se. These salts are used as starting materials in a process of catalytic reduction with tritium to give the corresponding tritium-tagged compounds (see Group XL(a)).

[Class 20(ii)] Apparatus for use in bricklaying comprises clips to be engaged upon bricks in previously laid rows and one or more guide rails of L-section fitted to the said clips to indicate the proper positions for laying bricks and the thickness of the mortar to be spread on them. In one form, Fig. 1, a clip comprises a scissor-like arrangement of levers 1, 9 pivoted at 3 and contracted by a spring 13, whereby a previously laid brick course is clipped between a bracket 12 on the upper lever and a bracket 16 bolted to the lower lever. One end of the lower lever has an upward extension 5 to which a guide rail 8 is clamped in a clamp 6, the guide rail being L-shaped and its horizontal flange giving the thickness of mortar to be laid. Additional support is provided by a pin 18, mounted on a plate 19 secured by a thumb screw, which passes through the bottom lever and can be pushed into the mortar joint between two courses of bricks. The position of the pin 18 can be adjusted to that of the mortar joint by moving it in an arcuate slot 17 in the lever 1. In another form, Figs. 3 and 5, a clip comprises a plate 20 carrying a spring member 21. The limbs of which pass through slots in the plate and are bent over at their extremities to form gripping fingers 22, and a screw-threaded pin 24. The gripping fingers 22 are placed over the top of a brick in the previously laid course and the pin 24 is inserted in the mortar below it, and the clip is held in place by the pressure of the spring member 21. A horizontal guide rail 26 of L- section is held in a groove in the top edge of the plate 20 by tightening screws 27, and vertical guide rails may be held in slots in the side edges of the plate, e.g. the guide rail 30, which is held by tightening screws 29. A horizontal guide rail may be joined to a vertical guide rail at a corner by a jointing device 31. The position of the pin 24 may be varied by providing holes for it in a block attached to the vertical guide rail 30. Spirit levels 35 may be placed on the clips and guide rails. The Provisional Specification mentions that the spring clips can be replaced by uprights carrying U-shaped guides and attached to a gantry for steadiness, the U-shaped guides being inverted and their legs carrying angle irons on both sides of the bricks. The Provisional Specification also mentions a mortar spreader comprising three detachable parts, viz. on one side of the bricks a brake lever pivoted to a handle, on the other side an L-shaped guide rail, and a connecting piece on which a hopper may be mounted. The spreader is held to the guide rail of the clips by the brake, under the pressure of a spring, and can be slid along the guide rail when the spring is released.
