What is 4-Hydroxy-2-butanone?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 4-Hydroxy-2-butanone which has developed particularly rapidly in recent years. Do you know about 4-Hydroxy-2-butanone?
The official answer:4-Hydroxy-2-butanone is a chemical substance that is obtained by the reaction of acetone and formaldehyde. The formaldehyde solution is mixed with acetone at 1:30 (w/w) and sent to a pipeline reactor at 51-53°C with a residence time of 3-4 min. In the production of methyl vinyl ketone, an intermediate of vitamin A, the resulting 4-hydroxy-2-butanone reaction solution is used directly in the next process and dehydrated with oxalic acid to obtain methyl vinyl ketone. The component used for the trapping of bark beetle powder, in complex with Ziegler-Natta catalyst, was used as a catalyst for the stereospecific polymerization of butadiene and as an intermediate in organic synthesis.
What’s the application of 4-Hydroxy-2-butanone?
Components for bark beetle powder trapping, complexes with Ziegler-Natta catalyst for stereospecific polymerization of butadiene, and intermediates for organic synthesis
Use water mist, dry powder, foam, or carbon dioxide extinguishing agents to extinguish fires.
Avoid using direct running water to extinguish the fire, which may cause the splashing of combustible liquids and spread the fire.
Contain the spill to avoid contaminating the environment. Prevent spills from entering sewers, surface water, and groundwater.
Reception and removal methods for spilled chemicals and disposal materials used.
Small spills: Collect spilled liquid in a sealable container if possible. Absorb with sand, activated carbon, or other inert materials and move to a safe place. Flushing into sewers is prohibited.
Large spills: Construct an embankment or dig a pit to contain it. Seal drainage pipes. Cover with foam to inhibit evaporation. Transfer to a tanker or special collector with explosion-proof pump, recycle or transport to waste disposal site.
