摘要： A process for the conversion of alkyl aryl compounds to alkynyl aryl compounds which comprises subjecting said alkyl aryl compounds to chlorination under conditions suitable for the dichlorination of at least one carbon atom of an alkyl substituent to said alkyl aryl compound or monochlorination of adjacent carbon atoms of said alkyl substituent, subjecting the resulting chlorinated alkyl aryl compound to dehydrochlorination in the presence of a basic medium, and thereafter recovering alkynyl aryl compounds.

摘要： 1,181,372. Titanium dioxide compositions. COSDEN OIL & CHEMICAL CO. 7 Feb., 1967 [8 Feb., 1966], No. 5727/67. Heading C3P. The greying of titanium dioxide pigmented compositions imparted during abrasive mixing, i.e. dry mixing in contact with metallic surfaces under conditions where the metal rubs off and discolours the pigment, is reduced by carrying out the mixing in the presence of up to 1% by wt. of a friable, dust-forming, colourless, alkaline inorganic solid containing or producing during the mixing particles having a size of less than 60 mesh U.S. Standard Sieve. The solid may be sodium hydroxide, calcium oxide, barium oxide, strontium oxide, magnesium oxide, calcium hydroxide, sodium bicarbonate, potassium carbonate, or sodium aluminate or borate and may contain an oxidizing agent, e.g. potassium persulphate or hydrogen peroxide. The composition may comprise particles, e.g. beads, of polystyrene.

摘要： A process is disclosed for producing composite sheeting of polystyrene having a thin protective layer of an acrylic ester polymer. The process comprises joining a molten stream of each polymeric material in a single extruder discharge conduit such that there is produced a single molten stream having a reasonably well defined interface between the two types of polymeric material, and thereafter, passing the resulting single stream of material through a sheet-form extrusion die having its die lips generally aligned with the foregoing interface.

摘要： 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 conducted with the styrene oxide in liquid phase, in vapor phase, or in solution within an inert solvent. The conditions of reaction are maintained to achieve a mild decomposition, described as thermolysis, as contrasted to a drastic decomposition, a so-called pyrolysis.
摘要翻译： 在相对温和的温度条件下加热氧化苯乙烯以引起热解。 这种热解在反应产物中产生大量苯乙醛。 可以通过蒸馏程序或其他分离方法从粗反应产物中回收基本上纯的苯基乙醛，或者如果需要，可以将苯乙醛直接转化成粗反应产物以产生其缩醛。 氧化苯乙烯的热解过程可以用苯乙烯氧化物在液相中，气相或在惰性溶剂中的溶液中进行。 保持反应的条件以达到轻度分解，被描述为热解，与剧烈的分解（所谓的热解）相反。

摘要： A SCREW EXTRUDER FOR CONVERTING POLYSTYRENE BEADS INTO FOAM INCLUDING AN EXTRUDER SCREW HAVING A FIRST SCREW STAGE FOR RECEIVING POLYESTERS BEADS AND FOR COMPRISING AND MELTING THE BEADS TO FORM MELTED POLYSTRENE AND A SECOND SCREW STAGE FORRECEIVING MELTED POLYSTRENE FROM THE FIRST STAGE AND FOR DISTRUBING A BOWLING AGENT THROUGHOUT THE MELTED POLYRENE; AND A RING VALVE FOR CONTROLLING THE FLOW OF MELTED POLYSTYRENE FROM THE FIRST
STAGE TO THE SECOND STAGE AND THEREBY PREVENTING BACKFLOE OF THE BOWLING AGENT FROM THE SECOND STAGE INTO THE FIRST STAGE. THE FIRST SCREW STAGE OF THE EXTRUDER SCREW HAS A COMPRESSION RATIO OF ABOUT 3.5:1, AND COMPRISES A METERING SECTION, A TRANSITION SECTION THAT IS ABOUT 1.5 TIMES AS LONG AS THE METERING SECTION, AND A FEED SECTION THAT IS ABOUT 2 TIMES AS LONG AS THE METERING SECTION.-
