数据库记载的用途

• No information was located regarding the uses of dibenzofuran.
• Used as a component of heat-transfer oils (with biphenyl); suitable as a carrier for dyeing and printing textiles (combined with methylnaphthalenes); [HSDB] Used as insecticide; [Hawley]
• Textiles (Printing, Dyeing, or Finishing) [Category: Industry]
• ... Together with biphenyl, is a component of heat-transfer oils. When combined with methylnaphthalenes, it is suitable as a carrier for dyeing and printing textiles. ... Derivatives serve as intermediates for naphtol AS and chromium complex dyes.
• Dibenzofuran is present in coal tar at a level of about 1%. It is recovered from a wash oil fraction that boils between 275 and 290 °C (containing about 30% dibenzofuran). A redistillation step is largely successful in separating dibenzofuran from acenaphthene, which boils 7 °C lower. The technically pure compound is obtained through crystallization of the redistilled fraction.
• Fluorene and acenaphthalene (indicated by a higher melting point than 82.8 °C)
