Production of aromatic aldehyde
专利汇可以提供Production of aromatic aldehyde专利检索，专利查询，专利分析的服务。并且PURPOSE:To industrially and advantageously produce an aromatic aldehyde, by reacting an aromatic compound with carbon monoxide under ordinary pressure using a carbonyl complex of copper (I) or silver in a super-strong acids as a catalyst. CONSTITUTION:An aromatic compound (e.g. pseudocumene) is reacted with carbon monoxide in the presence of a catalyst consisting of a copper (I) carbonyl complex or silver carbonyl complex in a super-strong acid (especially a hydrogen fluoride-based super-strong acid has advantages in that the resultant product is readily separated and a catalyst layer is reusable after extraction with benzene) without pressurization to afford an aromatic aldehyde (e.g. 2,4,5- trimethylbenzaldehyde). Since the production process can be wholly performed under about ordinary pressure, equipment investment cost and operating cost are remarkably reduced to reduce product cost. Furthermore, purity of the product is increased. The resultant product can be utilized in the field of plastics, coatings, plasticizers, adhesives, dyes, etc.，下面是Production of aromatic aldehyde专利的具体信息内容。
