アセトアルデヒド

アセトアルデヒドは、無色の揮発性液体で、刺激的でフルーティーな臭気を有しています。沸点は20.2 ℃、融点は−123.5 ℃であり、水および一般的な有機溶媒のほとんどと混和します。アセトアルデヒドは脂肪族アルデヒドに分類され、工業的有機合成における主要な化学中間体として主に用いられます。その主な用途には、酢酸、酢酸無水物、エチル酢酸、ピリジン誘導体の製造が含まれます。また、ペンタエリスリトール、アルドル化合物、ならびに特定の医薬品および農薬の製造にも使用されます。典型的な応用分野には、ポリマー（例：ポリビニル酢酸）、コーティング材、および風味料が挙げられます。

Acetaldehyde can also be used as an odorant, and it found in nature in many foods such as ripe fruits, cheese and heated milk. acetaldehyde occurs naturally during fermentation, and low levels of acetaldehyde are to be found in certain foods. It is mainly used for preparation of citrus, apple, cream type essence, etc.Acetaldehyde is mostly used in acetic acid industry. Butanol and octanol are also the important derivatives of the acetaldehyde in the past. Nowadays, butanol and octanol are prepared by Propylene carbonyl synthesis method.Acetaldehyde is a very important raw material in the production of a large number of chemical products, for example paint binders in alkyd paints and plasticizers for plastics. Acetaldehyde is also used in the manufacture of construction materials, fire retardant paints and explosives, while its uses within the pharmaceutical industry include the manufacture of sedatives and tranquilisers, among other things. Acetaldehyde can also be used as a raw material in the manufacture of acetic acid, another platform chemical with many applications.Acetaldehyde is also used to produce pentaerythritol, peracetic acid, pyridine and its derivatives. Domestically produced acetaldehyde is mainly used as intermediate for the production of acetic acid. Only a small amount is used for the production of pentaerythritol, butanol, trichloroacetaldehyde, trimethylolpropane, etc.Acetaldehyde is primarily used to produce other chemicals, including acetal, Crotonaldehyde, acetic acid peroxide, hydroxyl acrylic nitrile, trichloroacetaldehyde, ethyl acetate, pentaerythritol, acetic anhydride, acetic acid, Glyoxal, phenyl acrolein, acetal, methyl ethylamine , diethylamine, α-Alanine, pyridine, α-methylpyridine, β-methylpyridine, γ-methylpyridine, etc.
