What is Levulinic acid?

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 Levulinic acid which has developed particularly rapidly in recent years. Do you know about Levulinic acid?


The official answer: Levulinic acid is an organic compound with the molecular formula C5H8O3. it is easily soluble in water and some organic solvents, but insoluble in gasoline, kerosene, turpentine, and carbon tetrachloride. It hardly decomposes by distillation at atmospheric pressure and loses water when heated for a long time to produce unsaturated γ-lactone.

What’s the application of Levulinic acid?

It is a kind of multifunctional compound containing carbonyl, α-hydrogen, and carboxyl groups at the same time. It is the basic raw material for synthesizing various light chemical products and has wide use-value in organic synthesis and industrial and agricultural industries and medicine. The hydrogenated product of levulinic acid, γ-pentyl lactone, is an advanced solvent and an intermediate in the production of synthetic rubber, cold plasticizer, and surfactant. Levulinic acid chloride can be used as a bacterial inhibitor for industrial recycled water. In agriculture, the amine salt of levulinic acid chloride is used as a herbicide and defoliant. In medicine, levulinic acid can be made anti-inflammatory drugs and intravenous injection using starch, glucose, cellulose raw materials by deep hydrolysis. Usually heated with hydrochloric acid (or sulfuric acid) or another hydrolysis catalyst in the presence of conditions via the generation step of 5-hydroxymethylfurfural, and then by the decomposition of 5-hydroxymethylfurfural to obtain levulinic acid, concentrated by filtration, and then reduced-pressure distillation or extraction method to produce finished products

It can be reacted as carboxylic acid and ketone, and various products can be produced through esterification, halogenation, hydrogenation, oxidative dehydrogenation, condensation, and other chemical reactions. They are used as plastic modifiers, solvents, pharmaceuticals, industrial chemicals, spices, pesticide intermediates, organic synthesis intermediates, polymer additives, lubricant additives, surfactants, printing inks, rubber additives, cosmetic additives (including shampoos and toiletries), etc.

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.
