製造方法
The preparation of 4-Hexylresorcinol involves two methods:
The reaction of caproic acid and resorcinol in the presence of a catalyst.
Reduction of hexanoylresorcinol with zinc amalgam and dilute hydrochloric acid.
一般的な説明
P-hexylresorcinol appears as pale-yellow viscous liquid (that becomes solid on standing at room temperature) or a peach colored powder. Pungent faintly fatty odor. Sharp astringent taste. (NTP, 1992)
空気と水の反応
Insoluble in water.
反応プロフィール
4-Hexyl-1,3-benzenediol may be sensitive to prolonged exposure to light. Incompatible with acid chlorides, acid anhydrides and oxidizing agents .
危険性
Irritant to respiratory tract and skin, concentrated solutions are vesicant.
火災危険
Flash point data for 4-Hexyl-1,3-benzenediol are not available. 4-Hexyl-1,3-benzenediol is probably combustible.
臨床応用
Hexylresorcinol, also known as 4-hexylresorcinol, is a white crystalline substance with a faint phenolic odor. When applied to the tongue it produces a sensation of numbness. It is freely soluble in alcohol but only slightly soluble in water(1–20,000 parts). Hexylresorcinol is an effective antiseptic,possessing both bactericidal and fungicidal properties.The phenol coefficient of hexylresorcinol against S. aureusis 98. As is typical for alkylated phenols, hexylresorcinol possesses surfactant properties. The compound also haslocal anesthetic activity. Hexylresorcinol is formulated into throat lozenges because of its local anesthetic and antisepticproperties. These preparations are probably of little value. Hexylresorcinol (in the concentration in thelozenge) is probably not antiseptic, and the local anestheticproperty can anesthetize the larynx, causing temporary laryngitis.
