安息香酸

安息香酸は、淡い快適な香りを持つ白色の結晶性固体で、中程度の揮発性を示します。融点は122 ℃であり、常圧下で容易に昇華します。これは芳香族カルボン酸であり、基本的な有機化学中間体です。工業的には、主にベンゾイルクロリド、可塑剤（例：グリコールエステル）、カプロラクタムの前駆体として用いられ、染料、過酸化物、医薬品の合成にも使用されます。その応用範囲は、食品保存料（ナトリウム安息香酸塩として）、農薬、コーティング材、ポリマー添加剤（特にポリエステル樹脂およびアルキド系配合物）に及びます。

1. Used as a chemical reagent and preservative.2. Benzoic acid is important type food preservative. Under acidic conditions, It has inhibitory effects to mold, yeast and bacteria , but the effect is weak acid producing bacteria. The most appropriate antimicrobial pH values is ranging from 2.5 to 4, generally lower, the pH value is appropriate from 4.5 to 5. In the food industry with plastic barrels concentrated fruit and vegetable juice, the maximum use amount shall not be over 2.0g/kg; in jam (excluding canned), (taste) juice drink, soy sauce, vinegar in the maximum dose of 1.0g/kg; in soft candy, wine, wine in the maximum dose of 0.8 g/kg separately; in the low salt pickled vegetables, the sauce, candied fruit, maximum dose is 0.5 g/kg; in carbonated drinks in the largest amount of use is 0.2g/kg. due to benzoic acid, slightly soluble in water, its use can be a small amount of ethanol enable dissolved. 3.Preservative; anti microbial agents.Due to the low solubility of benzoic acid and use shall be stirring, or dissolved in a small amount of hot water or ethanol. When used in the soft drink with fruit juice concentrate, for benzoic acid easy volatile with the water vapor, so often used in the sodium salt, besides the above sodium equivalent to benzoic acid 0.847g.4.Often used as a fixative agent or preservative. Also used as a fruit juice aroma conservation agents. As a perfume with perfume fragrance. Can also be used for chocolate, lemon, orange, berries, nuts, candied fruit type edible essence. Tobacco flavor is also commonly used.5.Benzoic acid and its sodium salt are food preservatives. Under acidic conditions, it has inhibition of yeasts and molds. When pH 3, antibacterial strength and when pH 6, many fungi effect is very poor, so the antibacterial optimum pH is 2.5-4.0. Benzoic acid is mainly used for the production of sodium benzoate preservatives, dyes intermediates, pesticides, plasticizers, mordant, medicine, spice and also can be used as alkyd resin and polyamide resin modifier for the production of polyester, terephthalic acid and used equipment, iron and steel anti rust agent.6.Mainly used for antifungal and antiseptic.7.Used in medicine, dye carriers, plasticizer, spices and food preservatives such as production, and can also be used to paint of alkyd resin performance improvement; used as pharmaceutical and dye intermediates, used for the preparation of plasticizer and spices etc., as well as equipment, iron and steel anti rust agent.
殺菌剤、殺虫剤：安息香酸塩、可塑剤、ベンゾイルクロライド、アルキド樹脂の製造に使用；食品保存料の製造、綿布印刷における染料固定剤、たばこの乾燥処理、香料・香水・歯磨き剤の製造、分析化学における標準物質としての用途がある。米国では現在登録されていない。安息香酸は、現在約12か国の欧州諸国で使用されている。
