Title: Improvements in or relating to halogenated silicon esters
IPC: C07F7/18
Filed: 1951-06-05
Abstract: The invention comprises organo-silicon compounds of the general formula R3SiO(CH2)xCl wherein R represents an alkyl or phenyl radical and x is an integer from 3 to 5, and a process for the preparation of the above compounds by reacting a chloro-alcohol of the general formula HO(CH2)xCl with a chlorosilane of the general formula R3SiCl or a disilazane of the general formula (R3Si)2NH, R and x having the above significance.  The former process may be carried out in the presence of an acid acceptor, e.g. ammonia, pyridine or other organic amine.  Both processes may be carried out in an inert solvent, e.g. benzene, hexane or diethylether.  The preferred reaction temperature is 30 DEG  C.  In the examples the following compounds are prepared: 3 - chloropropoxy - 1 - trimethylsilane, 4 - chlorobutoxy - 1 - ethyldimethylsilane, 4 - chlorobutoxy - 1 - trimethylsilane, 5-chloropentoxy-1-trimethylsilane, 5-chloropentoxy - 1 - phenyl - dibutylsilane and 5 - chloropentoxy - 1 - dimethylethylsilane. Specification 692,669 is referred to.  Silicon-containing Grignard reagents are prepared from organo-silicon compounds of the above general formula, where x is 4 or 5, by reaction with magnesium to form compounds of the general formula R3Si(CH2)x1MgCl, where R has the significance indicated above and x1 is 4 or 5. Compounds are prepared where R is methyl and x1 is 4 and 5. The Grignard reagents may be reacted with compounds which will normally react with Grignard reagents, e.g. allyl halides, aldehydes, ketones, esters, nitro compounds, sulphones, acyl halides and nitriles.  They may also be used to increase the length of a chain terminated with a functional group by a hydroxylated chain of from 4 to 5 carbon atoms, e.g. the Grignard reagent derived from the organo-silicon compound of the above general formula where R is methyl and x is 5, may be reacted with benzoyl chloride to form the compound (CH3)3SiO(CH2)5COC6H5 which on treatment with water gives a hydroxy ketone of the formula HO(CH2)5COC6H5 and hexamethyl disiloxane. A similar synthesis with acetone gives the dihydroxy compound HO(CH2)5 C(CH3)2OH.

In the machine shown, the grinding-wheel 4, carried on a reciprocating support 3, is moved to and fro over the work, which is carried by a rotary chuck 5; the driving-mechanism for moving the support 3 may comprise a reversing-gear as described in Specification 16213/15. The vertical shaft 18 of this mechanism is geared to a shaft 21, on which are mounted a hand-wheel 22, whereby the support may be moved to and fro by hand, and an angularly adjustable cam 45 for actuating a reversing-switch in the supply circuit of the magnetic chuck, so that the switch is operated at predetermined points in the movement of the support. The reversing-switch consists of a pair of bent metal arms 27, 28 provided with contacts at their ends, secured in a block 25 of insulating- material that is mounted to rock on a fixed stud 26, and two pairs of metal contact arms secured upon blocks 35, 39 of insulating-material fixed to the frame of the machine. The arms 27, 28 are rocked against the action of a spring by the cam 45. In one position, the cam moves the arm to complete the circuit through the contacts on the left-hand side of the apparatus to energize the magnet; further rotation of the cam brings the arms into a neutral position, and the circuit is then broken and the magnet de-energized. Still further rotation completes momentarily the circuit through the right-hand set of contacts to send a current through the magnet coil in the reverse direction for the purpose of neutralizing the residual magnetism of the chuck. The work is removed from the chuck by an arm 50, which is adapted to sweep across the surface of the chuck and which may be faced with a pad of cleaning- material. The arm is mounted on a vertical spindle rocked, through a pinion 60, toothed segment 61 and linkage 66, 67, by an adjustable dog 69 on the reciprocating-support 3 as this approaches the right-hand end of its travel, the return stroke being effected by a spring 70.
