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.

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
