Acetic acid, commonly known as acetic acid,English nameAcetic AcidWidely present in nature, it is aOrganic compounds, is an important oxygen-containing derivative of hydrocarbons and is a typical exampleOrganic acidAcetic acid is widely recognized asvinegarThe source of internal sourness and irritating odor. In the home, acetic acid is dilutesolutionOften used as a descaling agent. In the food industry, infood additivesIn List E260, acetic acid is a designated acidity regulator.

According to different concentrations, acetic acid is also known asIce acetic acid (100% acetic acid), acetic acid (common name), acetic acid, ice acetic acid, vinegar (food grade), ice acetic acid, ice acetic acid (food grade), acetic acid (anhydrous), acetic acid (food grade), acetic acid, 36%, acetic acid, 36%.

Acetic acid molecules contain two carbonsatomThe saturationcarboxylic acidYes, it ishydrocarbonThe Important Oxygen Contentderivative.functional groupbycarboxylBecause it is the main component of vinegar, also known asacetic acidFor example, in fruits orvegetable oilMainly due to itsCompound estersThe form of existence; It exists in the form of free acids in animal tissues, excreta, and blood. Ordinary vinegar contains 3% to 5% acetic acid. Acetic acid is a colorless liquid with a strong pungent odor. Melting point 16.6 ℃, boiling point 117.9℃，relative density1.0492(20/4℃）Density ratioThe water is large,Refractive index1.3716. Pure acetic acid can turn into ice at temperatures below 16.6 ℃solidTherefore, it is often referred to asGlacial acetic acid. Easy to dissolve inwater、ethanol、Etherandcarbon tetrachlorideWhen water is added to acetic acid, the total volume of the mixture decreases and the density increases until the molecular ratio reaches 1:1, which is equivalent to formingMonobasic acidThe original acetic acid CH ∝ C (OH) ∝, further diluted, no longer changes in volume.

Pure anhydrous acetic acid (glacial acetic acid) is colorlessHygroscopicityLiquid,freezing pointAt 16.6 ℃ (62 ℉), it solidifies into colorless crystals.

Although according to acetic acidaqueous solutionThe dissociation ability in it is aweak acidHowever, acetic acid hascorrosiveIts steam has a stimulating effect on the eyes and nose. Acetic acid is a simple carboxylic acid and an important oneChemical ReagentsAcetic acid is also used to producefilm stockWhat is neededCellulose acetateUsed with woodan adhesivePolyacetic acid in the middleethyleneEsters, as well as many synthetic fibers andTextile.

Based on the physical and chemical properties of acetic acid, our company has developed corresponding technical solutions to solve the storage and transportation problems of acetic acid. Its representative products mainly include steel lined polyethylenePE、 Steel lined polyolefin PO, steel lined polytetrafluoroethylene PTFE and other steel lined plastic acetic acid storage tanks, which can resist the corrosion of acetic acid on metal shells at different temperatures, have been prioritized by modern chemical enterprises.
