Title: 4,4-Dimethyl-1,3-dioxan prepn. - by reacting formaldehyde, isobutylene and acidic salt catalyst
Inventor: GORBUNOV B N
IPC: C07D319/06
Filed: 1974-07-01
Abstract: The cpd. 4,4-dimethyl-1,3-dioxan (I) is prepd. by reacting isobutylene with HCHO in aq. medium contg. inorg. salt of mineral acid which holds pH at 2.2-4.5, at 90-115 degrees C washing the org. phase with water and recovering the prod. (I). The sepd. aq. phase and the water wash may be combined and 85-90% distilled to produce a distillate contg. unreacted HCHO which may be recycled, and a residual oil layer (which contains some recoverable (I) produced during distillation) and a salt layer which is sepd. and recycled. Cpd. (I) is an inter. for isoprene, a monomer for stereo-specific polyisoprene rubber prodn. The process gives high yields (85-90% w.r.t. reacted HCHO) does not produce polluting waste water, and by-prod. 3-methylbutane-1,3-diol (II) is not discarded but converted to (I) during distillation. The preferred catalytic salts may be recovered since their stable acidity during distillation prevents resinification.

Title: Magnetic motor for conversion of magnetic to kinetic energy - has external stray magnetic field guided away by highly permeable U-pieces
IPC: H02K53/00
Filed: 1974-07-02
Abstract: The motor rotor consists of alternate sheets of magnetic and magnetically isolating material mounted around an axis so that, when seen from the side, they resemble a multipoint star.
