Title: Process for the production of esters and carboxylates of alkyl boric acids
IPC: C07F5/02
Filed: 1960-11-03
Abstract: Alkyl boric acid alkyl esters or aryl esters, or mixed anhydrides of alkyl boric acids and carboxylic acids, represented by the general formula: RnB(OR1)3-n wherein n is 1 or 2, R is an alkyl or cycloalkyl radical and R1 is an alkyl, cycloalkyl, aminoalkyl, alkylaminoalkyl, dialkylaminoalkyl, alkoxyalkyl, aryl, halogenoaryl, aminoaryl, acyl, aminoacyl, alkylaminoacyl or alkoxyacyl radical, are made by reacting an alkyl diborane RmB2H6-m wherein m is 1, 2, 3 or 4 and R has the meaning above, with an organic hydroxylic compound of the formula R1OH.  The reaction is advantageously effected at temperatures in the range -20 DEG  to +50 DEG C., but the reaction of alkyl diboranes and aminocarboxylic acids requires temperatures between 20 DEG  and 150 DEG C.  The reaction is preferably carried out in an inert gas atmosphere and in the absence of moisture.  Many examples of suitable reactants are given.  Special embodiments are the reaction of alkyl diboranes with alkoxy alcohols, aminoalcohols and aminocarboxylic acids with choice of the reactants so that co-ordination between the amino nitrogen or ether oxygen and the boron atom forms 5 or 6-membered rings and the products are stable against oxidation and hydrolysis.  Thus novel b ,b -dialkyl-O-alkylboro-2,6-dioxanes of the formula <FORM:0911290/IV (b)/1> wherein R1, R2 and R3 are alkyl radicals and R4 is H or an alkyl radical are made by the reaction of an alkyl diborane with a g -alkoxy alkanol.  Analogously, 5-membered rings are made from b -alkoxy alcohols.  The reaction of tetraalkyl-diborane with b - or g -amino alcohols leads to boro-oxazolidines or tetrahydro-boro-oxazines, and reaction with diethanolamines gives compounds having double rings. b -dialkyl-boro-oxazolidones and b -dialkyl-tetrahydroboro-oxazones or b -alkyldihydroboro-oxazones, are made by reaction of tetraalkyldiboranes with a -aminocarboxylic acids or b -aminocarboxylic acids.  Examples describe the preparation of the butyl, propyl, phenyl and 3-methoxybutyl esters of dipropylboric acid, dipropylmethoxyacetoboric acid and b -dipropylboronoxazolidone. Specifications 795,067 and 829,635 are referred to.

Abstract: 957,770. Tyre press. McNEIL MACHINE & ENGINEERING CO. Oct. 9, 1962 [May 2, 1962], No. 38162/62. Heading B5A. The bottom mould half 21 of a vulcanizing press for automatically curing partially preformed tyres, carries a cylindrical inflatable diaphragm 46 having a plano-convex end wall 48. The lower end of the diaphragm is secured to the mould half by a plate ring 53 and a bead ring 54 which are fixed to the upper end of a hollow cylinder 58. The diaphragm is extended and contracted by raising or lowering the plate 50 which is attached through rod 106 to a piston 105, which is reciprocable within cylinder 58. The upper mould half 20 is suspended by screw threaded members 36, 34 and a support 32, from the underside of a movable cross beam 22, and carries a hollow cylindrical member 125 which telescopes over the upper portion of the extended diaphragm as shown in Fig. 2. In the operation of the machine a partially cured tyre B is deposited around the extended diaphragm, upon the lower bead ring 54, and the press closed until the upper bead of the tyre is engaged by the upper bead ring 126 of mould half 20 (the position shown in Fig. 2). The movement of the cross beam is then halted and the diaphragm inflated, radial expansion of the upper portion being prevented by the cylindrical member 125. Shaft 133, operated by a suitable air bellows and toggle mechanism, is then lowered so that the plate 130, carried at the lower end thereof, forces the upper wall 48 of the diaphragm down until it is substantially level with the upper head ring 126 in which position the diaphragm is free from radial constraint. The press is then fully closed and the tyre completely cured. Specifications 652, 367, 704, 797, 714, 814, 799, 761, 831,768 and 865,447 are referred to.
