Title: Improvements in chromanes and method of producing the same
IPC: C07D311/72
Filed: 1939-05-22
Abstract: 529,082. Chromanes. MINNESOTA, REGENTS OF THE UNIVERSITY OF. May 22,1939, No. 15117. Convention date, May 31, 1938. Addition to 529,081. [Class 2 (iii)] Chromanes are prepared by a modification of the process disclosed in the parent Specification which comprises reacting at an elevated temperature a substituted or an unsubstituted hydroquinone or hydroquinone derivative which has 'vacant at least one position ortho to the hydroxyl group with a diene or with a compound containing diene linkage. The reaction is preferably carried out in the presence of an acid catalyst which may be an organic acid such as formic acid or acetic acid, a substituted organic acid such as a halogenated acetic acid, an inorganic acid such as sulphuric acid or phosphoric acid, or organic, or acidic, or inorganic salts such as amine salts, aluminium chloride, zinc chloride, mercuric chloride, acid sulphates or boron trifluoride. Starting materials mentioned include hydroquinones, substituted hydroquinones and hydroquinone monoethers. Diene compounds mentioned include dimethyl butadiene, isoprene, and phytadiene. The diene may be produced as a preliminary step in the procedure or it may be produced in situ in the principal reaction. There may be used any alcohol such as an alkylic alcohol, or any compound which will produce a diene constituent either directly by the use of acid catalysts with or without heat, or after rearrangements in the presence of acids. There is particularly mentioned the use of an ene-ol such as primary alkylic alcohols having the general structure or teriary alkylic compounds having the general structurewhere X may either be a hydroxyl group or a substituted hydroxyl group. There may also be used as the source of the diene component a 1:2-, or a 1:3- disubstituted hydroxyl or halogen compound. In this modincstion, the diene yielding compound is substituted for the diene in the general reaction, and as the diene is formal its rests. In examples (1) dimethyl butadiene is reacted with hydroquinone monomethyl ether in the presence of mercuric chloride first on a water bath, and then on a wire gauze at 240‹ C. The reaction product is taken up in ether, washed with alkali and then with water. (2) Dimethyl butadiene is reacted with hydroquinone monomethyl ether in glacial acetic acid solution saturated with dry hydrogen chloride. The product is worked up as in example (1). (3) Trimethyl-hydroquinone is reacted with isoprene in glacial acetic acid solution in the presence of zinc chloride. The reaction product is poured into water and the other solid precipitate re-crystallized from alcohol. (4) Phytadiene is substituded for dimethyl butadiene in example (1), the reaction being otherwise similar. (5) Nerolidol which is the alkylic isomer of tetrahydrofarnesol may be substituted as a diene in any of the examples 1-4. A particular reaction of this compound with trimethyl hydroquinone in a mixed formic acid-acetic acid solution is described.

All the parts may be cemented or otherwise secured together. It is also proposed to form the base member as part of the palate of the denture, (see Fig. 4, not shown), and in a further modification the socket is formed in the base part and the spigot in the crown, (see Fig. 5, not shown), this arrangement giving the possibility of increased movement.

Class 59 [Also in Group XXXIV] A ball mill designed to receive and discharge material continuously during operation, comprising a bowl C adapted to contain grinding balls and rotatable simultaneously about its own axis Y and about a convergent axis X has a feed plate 58 at or near the point of intersection Z of the axes X and Y for receiving material fed into the bowl through an inlet 59 and throwing it outwardly against the grinding balls. The two rotations are preferably in opposite senses. The bowl is rotatably mounted on a sub-frame B which is rotatably mounted on the main frame A of the mill. The sub-frame is driven from a motor through bevel gears 25, 26 and a pinion 23 which meshes with a gear 22 secured to the hub 14 of a spindle H. The bowl is driven from another motor through bevel gears 25a, 26a and a pinion 40 meshing with a gear wheel 41 on a shaft 42 which carries at its upper end a pinion 43 which meshes with an idler gear wheel 44 in turn meshing with a gear wheel 45 secured to the hub 14a of the bowl spindle F. Ground material is discharged from the bowl through a series of circumferentiallyarranged arcuate passages G. Lubricating oil supplied from a pump through an inlet branch 5a passes upwardly through an axial oil passage 42a in the shaft 42 and escapes through a top fitting 61 which has a pin hole from which an oil jet is delivered upwards through the top wall 31 of the sub-frame B. This oil jet lubricates the bowl roller bearings in the sub-frame and is then flung downwards and outwards through apertures 31a into the interior of the sub-frame. A pump 62 recirculates oil which tends to collect near the walls of the sub-frame. In a modification, Fig. 6 (not shown), outlets for ground material are provided both at the top and bottom of the bowl which contains balls of three different sizes. In a further modification, Fig. 7 (not shown), the bowl is provided at different heights thereof with supplementary discharge holes.
