Tung tung oil originating in the Yangtze River basin, the introduction of Taiwan has been for centuries, mainly used to squeeze tung oil. Tung oil on the classification of the genus Euphorbia plants Kojo wood, wood tung Taiwan (Millennium Tong, peel wrinkles), and tung oil tree (three Tong, smooth skin) two varieties. Tung tree growing fast, do furniture, matchsticks, toothpicks, etc., but also an ideal material for matches and paper industry. Jatropha oil extraction mainly to picking fruit, the fruit can be used to extract good waterproof tung oil, a well-known international oil Mino waterproof paper umbrellas umbrella used, that is, tung oil, in addition to the chemical, unlike now, when so advanced tung corrosion, is an important raw material for paint. According to experts, most of Taiwan's oil tung tung wood used in construction, mostly tung, tung oil accounts for about 90%: compound classification is according to the classification of molecules of different compounds. [2-3] according to different classification chemical properties: can be divided into oxide compounds, acids, bases and salts. According to whether or not containing hydrocarbon elements Category: organic: organic compounds containing hydrocarbons (or called hydrocarbons, hydrocarbon), such as methane (methane, CH4), divided into: carbohydrates, nucleic acids, lipids and proteins. Is a carbon-containing organic compound of an element (other than CO2, CO, H2CO3 and outer carbonates) such as CH4, C2H5OH, CH3COOH contain carbon (C) element. [4] inorganic compounds: inorganic compound does not contain hydrocarbons, such as lead sulfate [lead (II) sulphate, PbSO4] tung oil manufacturers, are divided into: acids, bases, salts and oxides. Again as H2O, KClO3, MnO2, KMnO4, NaOH, etc., are inorganic. [4] classified by the type of chemical bond: ionic compounds: Sodium is a metallic element, chlorine is a nonmetallic element. Sodium and elemental chlorine is very easy to react chemically with other substances. From each other when they are chemical reaction to produce a compound of sodium chloride.
