Styrene oxide is heated under relatively mild temperature conditions to cause thermolysis. Such thermolysis produces substantial quantities of phenylacetaldehyde in the reaction product. Substantially pure phenylacetaldehyde may be recovered from the crude reaction product by distillation procedure, or other separation means, or, if desired, the phenylacetaldehyde may be directly converted in the crude reaction product to produce its acetals. The process of thermolysis of styrene oxide may be co...

A treating liquid for depositing a hydrated metal oxide comprises a basic aqueous solution of an oxide of an amphoteric metal and a pH reducing reactant that subsequently lowers the pH of the solution to one at which a hydrated oxide of the amphoteric metal is precipitated. The treating liquid can provide a single step process for consolidating or plugging a sand and/or can comprise a sand consolidating or plugging component of a drilling, fracturing, perforating, oil-displacing, or the like, ty...

A process for the preparation of active magnesium oxide having a large specific area by dispersing magnesium hydroxide or oxide with water forming a turbid liquid having a turbidity density of about 5 to 20 percent and vigorously agitating the liquid for about 5 to 60 minutes, the temperature of the turbid liquid being kept at about 80.degree. to 110.degree. C throughout the process, by introducing steam, washing the filter cake, drying and calcining the separated magnesium compound to obtain la...

A metal oxide varistor has a high thermal conductivity potting material encapsulating completely the metal oxide varistor and a portion of the leads therefrom, a pair of metal plates spaced in a generally parallel reslationship to the opposite major surfaces of the varistor and bonded thereto by the potting material, and one of the plates having at least a pair of mounting holes therein or other suitable means.

Titanium dioxide pigment is coated with one or more substances selected from hydroxides, hydrous oxides, phosphates, and basic sulphates, and the coated pigment is subjected to hydrothermal pressure treatment by being maintained at a temperature of at least 50.degree.C. in contact with liquid water, with a total ambient pressure of greater than one atmosphere.

Non-oxide glass composition of BeTe 60%, TiS.sub.2 10 percent, Li.sub.2 S 10 percent, K.sub.2 S 10 percent and Cs.sub.2 S 10 percent by weight.

Compacted, sintered cupric oxide masses are disclosed. The masses are prepared from copper oxide powder under high pressure followed by heating at high temperatures. Various regions of the mass can be switched to an electrically conductive copper state. This invention could easily be used for the storage of electrical information as well as for optical memory.

A method for preparing propylene oxide by oxidizing propylene with atmospheric oxygen in the presence of oxyfluoride derivatives of molybdenum or tungsten, or mixtures thereof, for example, (Me).sub.2 MoO.sub.2 F.sub.4, (Me).sub.2 WO.sub.2 F.sub.4 or (Me).sub.3 W.sub.2 O.sub.4 F.sub.7, where Me is NH.sub.4, K, Rb or Cs. The oxidation is carried out in organic solvents oxidizable to hydroperoxides, for example ethylbenzene, isobutane and isopentane.
