What is sour anhydride?
Acidydride of acid is any member of the group of organic chemicals with molecules that include oxygen atom simultaneously linked to two groups of atoms called the acyl groups. There are a number of different types of acid anhydride, with properties that differ according to their different acyl groups. Many of them are produced and used in the modern industry. Acyl groups are functional groups containing carbon atom, oxygen atom and an alkyl group that refers to a set of functional groups composed exclusively of carbon atoms and hydrogen connected by individual links. Both acyl groups are, in turn, a one -time oxygen atom. There are many possible acyl groups that can connect with oxygen and thus many different acidic anhydrides with different chemical properties. Most types of acid anhydride are symmetrical, with an oxygen atom associated with the same functional groups, but there are excitation.
acid anhydrides differ in their properties. Some are solid at room temperature, usually in the form of pellets or flakes, while others are liquids. In general, it is clear whether liquid and white, if they are solid and often produce pungent, pungent odors when they are exposed to air. They can cause irritation or burns if they get into contact with their eyes or skin, irritation or lung damage if their vapors are inhaled and burn into the gastrointestinal tract if swallowed. Excessive exposure without proper medical care can cause serious injury or death.
Most often acid anhydrides are derived from chemical reactions including carboxylic acids, groups of organic acids. The name of the resulting anhydrides of acid is also commonly derived from the name of the original acid. For example, a condensation reaction involving two Calle carboxyl acid molecules D octic (CH 3 COOH) results in one water molecule (H 2 o) and the molecule of the ocute anhydride ((ch 3 Co) 2 o). Some forms of acidic anhydride consist of other types of organic acids, such as phosphonic and sulphone acids or inorgan acids such as phosphoric acid (H 3 4 ).
). ). ).In the modern industry, several acid anhydrides are used. Acetic anhydride is commonly used as an agent for reactions involving certain organic compounds and is involved in the production of aspirin and cellulose acetate, which is used as a synthetic fiber and as a substrate or base for photo -sensitive chemicals in photographic film. Another example is the maleic anhydride (C 2 h 2 (CO) 2 o), which is used in the production of polyester resins in forming compounds and toner for laser printers and photocap.
