摘 要:以檸檬醛和丙酮為原料,在氫氧化鈉催化條件下,經(jīng)羥醛縮合反應先制備假性紫羅蘭酮,再在磷酸催化條件下,經(jīng)環(huán)化反應制備紫羅蘭酮。采用正交法研究了一鍋法條件下,檸檬醛合成紫羅蘭酮工藝條件。合成假性紫羅蘭酮優(yōu)化工藝條件是:物料比n(檸檬醛) ∶ n(丙酮)=1 ∶ 6,催化劑用量比w(10%NaOH) ∶ w(檸檬醛)=4%,反應溫度60℃,反應時(shí)間3 h。合成紫羅蘭酮優(yōu)化工藝條件:物料比n(檸檬醛) ∶ n(H3PO4)=1 ∶ 1,反應溫度40℃,反應時(shí)間3 h。
關(guān)鍵詞:檸檬醛;紫羅蘭酮;正交法

Abstract:The pseudoionone was synthesized from citral and acetone by aldol condensation using sodium hydroxide as catalyst. The ionone was synthesized by cyclization using phosphoric acid as catalyst. The optimized synthesis technology of ionone from citral by one step were studied using orthogonal method. The optimized synthesis technology of pseudoionone were as following: mole ratio of citral to acetone was of 1:6, mass ratio of 10% sodium hydroxide to citral was of 4%, reaction temperature was of 60℃, reaction time was of 3 h. The optimized synthesis technology of ionone were, mole ratio of citral to phosphoric acid was of 1∶6, reaction temperature was of 40℃, reaction time was of 3 h.
Key words:citral; ionone; orthogonal test
