1,3-dioxane Preparation Method

1,3-dioxane ring preparation process is concentrated formaldehyde and ethylene glycol with concentrated sulfuric acid as a catalyst in the reactor at 90 ~ 110 ℃ under atmospheric pressure reaction, and then distilled from the top of the distillation column 70 ~ 74 ℃ azeotrope, salted out by sodium chloride, solid alkali drying, re-distillation of the reboil and light bulb after removal of products.
If you need to prepare 1,3-dioxetane, you can contact us, we have 1,3-dioxane plant, and easy to operate, safe and reliable.

How Is The Separation Process Of Fusel Oil?

图片
 Fusel oil is a byproduct of the alcoholic fermentation process, composed of several alcohols, including amyl alcohol, isoamyl alcohol, propanol, and butanol. The separation of fusel oil from the main product, ethanol, is a critical step in the production of high-quality spirits and fuels. This article delves into the methods and processes involved in the separation of fusel oil, highlighting the techniques, challenges, and advancements in the field.   Understanding Fusel Oil Composition of Fusel Oil Fusel oil  consists of higher alcohols, which are formed during the fermentation of sugars by yeast. These higher alcohols include: - Amyl Alcohol - Isoamyl Alcohol - Propanol - Butanol   These compounds have higher boiling points than ethanol, making their separation crucial to ensure the purity and quality of the final product.   Importance of Separation Separating fusel oil from ethanol is essential for several reasons: - Quality Control: Ensures the final produc...

Use Of Hydrogen Peroxide As Bleaching Agent In Paper And Pulp Industry

图片
  Measuring Hydrogen Peroxide in the Paper and Pulp Industry   Hydrogen peroxide is one of the most common bleaching agents. It is used as the primary bleaching agent in the textile industry, and is also used in pulp, paper, and many home laundry applications. Alkaline hydrogen peroxide is used as a bleaching agent for the mechanical pulp. The amount of base such as sodium hydroxide is less than that which is used in bleaching chemical pulps and the temperatures are lower.   How Can Hydrogen Peroxide Be Used as a Bleaching Agent?   In the textile industry, it is commonly used for bleaching cotton fabric. The addition of magnesium sulfate in the bleaching formula helps stabilize the bleaching system for cationized cotton, improving whiteness index and fabric strength. In the pulp and fiber industry, hydrogen peroxide is used to eliminate lignin content and achieve high color brightness. The concentration of hydrogen peroxide used affects the degree of whiteness and fa...

Three Most Common Methods of Wastewater Treatment

图片
With the continuous scale development of urban industrial production, factories in the production process continue to discharge a large amount of sewage to the outside world, which has caused very bad pollution to the environment, so there are those simple methods of sewage treatment? Today   Sanli Fengxiang   will introduce to you the three most common treatment methods!   According to its principle of action can be divided into the physical method, biological method and chemical method of these three.   Physical Method The main use of physical action to separate the non-soluble substances in the sewage, in the treatment process does not change the chemical properties. Commonly used are gravity separation, centrifugal separation, reverse osmosis, air floatation, etc.. The physical method treatment structures are simpler and more economical, and are used in cases where the capacity of the village water body is large, the self-purification capacity is strong, and...
