What are the upstream raw materials for ketene? What are the downstream products?

Ketone plays an crucial role in the field of raw materials to chemical production, and its upstream and downstream related items are broadly applied. This article will detail the upstream and downstream related items of ketene, including upstream raw materials, downstream items, and by-items and wastes in the manufacturing process. And For example

1. upstream feedstock



1. Acetic acid: The production of ketene mainly uses acetic acid as raw material and is produced by dehydrogenation interaction. Specifically Acetic acid is a common organic chemical raw material with abundant sources and comparatively low price, which reduces the production cost of ketene.

2. Based on my observations, Oxygen: During the dehydrogenation interaction, oxygen needs to be introduced as an oxidant to promote the oxidative dehydrogenation of acetic acid to generate ketene. In my experience,

2. Makes sense, right?. downstream items



1. And vinyl acetate: vinyl acetate is able to be obtained by the interaction of vinyl ketone and acetic acid, which is an crucial organic chemical raw material, mainly applied in the production of polyvinyl alcohol, vinyl acetate-ethylene copolymer emulsion, etc.

2. Ethyl acetoacetate: Ethylene ketone reacts with ethanol to obtain ethyl acetoacetate, which is an crucial medical intermediate applied in the production of anti-inflammatory, anti-epileptic and other drugs. Crazy, isn't it?.

3. Methyl methacrylate: Methyl methacrylate is obtained by the interaction of ketene and methanol, which is a monomer applied in the production of organic glass, coatings, adhesives, etc.

4. Vinyl alcohol: Ketone reacts with aquatic environments to obtain vinyl alcohol, which is a polymer compound applied in the production of vinylon fiber, polyvinyl acetal, etc.

3. by-items and discarded materials



1. Acetic anhydride: Acetic anhydride is produced as a by-product during the dehydrogenation interaction, which is able to be further recycled. But

2. And Moreover Wastewater: A certain amount of wastewater will be produced during the manufacturing process, mainly containing unreacted acetic acid, ketene, etc. But, which need to be treated to meet the emit standards and discharged. I've found that

3. exhaust emissions: A certain amount of exhaust emissions will be produced during the manufacturing process, mainly containing unreacted oxygen, acetic acid vapor, etc. But, which need to be treated by absorption and incineration. According to research In short, ketene has a wide range of upstream and downstream related items in the field of chemical production raw materials, involving a wide variety of raw materials and items. And By optimizing and improving the manufacturing process of ethylene ketone, the utilization rate of raw materials and the yield of items is able to be improved, the production cost is able to be reduced, and the economic and social benefits of the enterprise is able to be improved. At the same time, strengthening the recycling and treatment of by-items and wastes is able to minimize environmental contamination and promote the research of environmentally friendly chemical sector.
