DIBK (diisopropyl ketone) is an important raw material for chemical production, which is widely used in medicine, pesticide, spice and other fields. This article will introduce the manufacturing method of DIBK, including raw material preparation, reaction process, post-treatment and so on.
1. Raw Material Preparation
The main raw materials for the manufacture of DIBK are acetone and isopropanol. In order to ensure the quality and yield of the product, it is necessary to select high quality raw materials and ensure that its purity and moisture content meet the requirements.
2. reaction process
The manufacturing process of DIBK mainly uses ketonization reaction, that is, under the action of acidic catalyst, acetone and isopropanol are condensed to generate DIBK and water. Commonly used acidic catalysts include sulfuric acid, hydrochloric acid, and the like.
In the reaction process, it is necessary to control the appropriate reaction temperature and time to ensure the progress of the reaction and the quality of the product. At the same time, it is necessary to pay close attention to the pH value and moisture content of the reaction solution, and adjust the amount of catalyst and reaction conditions in time.
3. post-treatment
After the reaction is completed, the reaction solution needs to be post-treated to obtain pure DIBK product. Common post-treatment methods include distillation, extraction, crystallization, etc. Among them, distillation is the most commonly used method. DIBK can be separated from water by heating and condensing to obtain a product with higher purity.
in the post-processing process, need to pay attention to control the operating temperature, pressure and other parameters to avoid product decomposition and loss. At the same time, the equipment needs to be cleaned and maintained regularly to ensure the normal operation of the equipment and the quality of the product.
In short, the manufacturing process of DIBK requires strict control of factors such as raw material quality, reaction conditions and post-treatment processes to ensure product quality and yield. At the same time, it is necessary to strengthen the supervision and management of the production process to ensure the safety and stability of production.
