| | 4-ヒドロキシ安息香酸2-エチルヘキシル Usage And Synthesis |
| 外観 | 無色～わずかにうすい黄色, 澄明の液体 | | 溶解性 | アルコール類, エステル類, ケトン類, 及び一般有機溶剤に溶解するが, 水には不溶。エタノール及びアセトンに溶け、水にほとんど溶けない。 | | 用途 | 保存料。 | | 特性 | The characteristics of 2-Ethylhexyl 4-hydroxybenzoate are: with the increase of the alkyl group in the paraben, the water solubility gradually decreases, the fat solubility increases gradually, the toxicity also decreases, and the antibacterial activity increases , in which esters of alkyl carbon chains with 11 and 12 carbons have the greatest antibacterial activity. | | 使用 | 2-Ethylhexyl 4-hydroxybenzoate is a broad-spectrum, high-efficiency, low-toxicity food preservative, and one of the three major food preservatives recognized internationally. | | 定義 | ChEBI: 2-Ethylhexyl-4-hydroxybenzoate is a benzoate ester. | | 合成 | Synthesis of 2-Ethylhexyl 4-hydroxybenzoate usually uses p-hydroxybenzoic acid (P-hydroxybenzoic acid) and the corresponding alcohol for esterification to azeotrope with water agents (such as petroleum ether, benzene, toluene, cyclohexane, etc.) |
