    摘要: The invention provides a method for manufacturing a large scale quartz glass slab ingot in a flame hydrolysis reaction in a furnace, including the steps of rotating the furnace, depositing a fused silica on a furnace bed, and extending the deposit outwardly by heating and rotation of the furnace, thereby a quartz glass slab ingot is obtained. A quartz glass burner is installed at the ceiling of the furnace, hydrogen gas supplied to the burner flows down along the tapered wall of the oxygen chamber and is ejected into the outer casing. Part of the hydrogen gas is deflected to the center of the burner and mixed with the oxygen just after the ejection from the oxygen gas nozzles. Thereby, the flame is formed smoothly and the thermal efficiency is improved. The flame becomes wide enough and the silica powder transported by the hydrogen gas is uniformly fused by the flame and heat capacity of the fused silica.

    摘要: The invention provides a process for easily, efficiently and economically preparing bis(trifluoromethylphenyl)methanol from either toluoyl chloride or a trihalomethylbenzoyl chloride. First the starting compound is reacted with toluene in the presence of a strong acid catalyst such as a perfluoroalkylsulfonic acid to form a benzophenone derivative, CX.sub.3 C.sub.6 H.sub.4 --CO--C.sub.6 H.sub.4 CH.sub.3, wherein X is H, F, Cl or Br. Next, by chlorination the benzophenone derivative is converted into CY.sub.3 C.sub.6 H.sub.4 --CO--C.sub.6 H.sub.4 CCL.sub.3, wherein Y is F or Cl, and then the chlorinated intermediate is fluorinated into bis(trifluoromethyl)benzophenone. By reduction of carbonyl group of this benzophenone derivative the aimed compound is obtained.
