Title: Grain refinement of cast metals
Inventor: CAMPBELL JOHN
IPC: B22D27/02
Filed: 1970-03-23
Abstract: 1335383 Casting processes and apparatus BRITISH IRON & STEEL RESEARCH ASSOCIATION 19 April 1971 [23 March 1970] 13922/70 Heading B3F [Also in Divisions B1 and H5] Metals which solidify with a dendritic structure, e.g. steel, aluminium, are given a finegrained structure by stirring the melt whilst solidifying to break up dendritic growth. The stirring is produced by passing an electric current through the melt in the presence of a stationary magnetic field and is such that the melt in one plane rotates in one direction whilst the melt in an adjacent plane rotates in the opposite direction thus producing sufficient turbulence between the planes to break up dendritic growth. In an electroslag refining process, a consumable steel electrode 3 is fused into a molten slag bath within a cylindrical mould 17 of non-magnetic material. The mould 17 is cooled by a water-spray or cooling jacket and rests upon a water-cooled stool 2. An electric current is passed from the electrode 3 to the stool 2 but the mould 17 is insulated from the stool to ensure vertical current flow. About the central portion of the stool is a magnetic field producing coil 4 which may or may not be connected in series with the electrode current supply. Both the coil 4 and the electrode 3 are vertically movable on screwjacks 6, 7, 8, 9. The metal above and below the coil 4 rotates in opposite directions 15, 16. The coil 4 is moved upwards as electrode melting proceeds. The process can also be applied to vacuum arc refining apparatus using a consumable electrode and to directional solidification apparatus where the melt is heated by current from a non- consumable electrode.

Abstract: A novel multi-step process for preparing the (4S &cir& _-enantiomer of 4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone in a highly-optically pure form is disclosed. The process involves (1) first esterifying 4-(3,4-dichlorophenyl)-4-ketobutanoic acid with isopropylene or isobutylene to form the corresponding isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-4-ketobutanoate; (2) then reducing the ketobutanoic acid ester obtained in the first step with an asymmetric carbonyl reducing agent to form the corresponding chiral isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-(4R &cir& _)-hydroxybutanoate; (3) then sulfonylating the (4R &cir& _)-hydroxybutanoic acid ester with methanesulfonyl, benzenesulfonyl or p &cir& _-toluenesulfonyl chloride or bromide in the presence of a standard base to yield the corresponding isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-(4R &cir& _)-sulfonyloxybutanoate; (4) next subjecting the 4-sulfonyloxybutanoic acid ester obtained in the third step to a copper-coupling reaction with dilithium diphenyl(cyano)cuprate of the formula  PHI 2Cu(CN)Li2 to effect a stereochemical displacement of the organic (4R &cir& _)-sulfonyloxy group of the (4R &cir& _)-sulfonyloxybutanoic acid ester by the phenyl group of the dilithium diphenylcuprate reagent and so selectively form the corresponding isopropyl or t &cir& _e &cir& _r &cir& _t &cir& _.-butyl 4-(3,4-dichlorophenyl)-(4R &cir& _)-phenylbutanoate, and (5) thereafter cyclizing the stereospecific (4R &cir& _)-phenylated n-butanoic acid ester in the presence of a protic or Lewis acid catalyst to finally yield the desired (4S &cir& _)-4-(3,4-dichlorophenyl)-3,4-dihydro-1(2H)-naphthalenone compound in a highly-optically pure form. The latter compound, which is a novel (4S &cir& _)-enantiomer per se, has utility as an intermediate that ultimately leads to pure c &cir& _i &cir& _s &cir& _-(1S &cir& _)(4S &cir& _)N-methyl-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-1-naphthaleneamine (sertraline), which is a known antidepressant agent. The aforementioned isopropyl and t &cir& _e &cir& _r &cir& _t &cir& _.-butyl esters of 4-(3,4-dichlorophenyl)-(4R &cir& _)-hydroxybutanoic acid, as well as their corresponding (4R &cir& _)-methanesulfonyl, (4R &cir& _)-benzenesulfonyl and (4R &cir& _)-p &cir& _-toluenesulfonyl derivatives, are also novel compounds, as are the aforementioned isopropyl and t &cir& _e &cir& _r &cir& _t &cir& _.-butyl esters of 4-(3,4-dichlorophenyl)-(4R &cir& _)-phenylbutanoic acid as well as the aforesaid acid per se.
