Daim ntawv thov:

Trans-4-Methoxycinnamic Acid (CAS: 943-89-5), Esters muab tau los ntawm trans-4-methoxycinnamic acid yog cov absorbers zoo ntawm UV hluav taws xob.Ua hauj lwm hauv cov organic synthesis ntawm kws tshuaj intermediates, hluavtaws anti-adrenergic tshuaj esmolol, tshuaj pleev ib ce ultraviolet absorption.Kuj tseem siv los ua tshuaj reagent.
Tam sim no, feem ntau siv 4-Methoxycinnamic Acid tshuaj pleev thaiv hnub yog p-Methoxycinnamate octyl, uas yog cov kua tsis muaj xim lossis lub teeb daj, insoluble hauv dej, soluble hauv cov kuab tshuaj organic xws li ethanol thiab ethyl acetate, Nws tsis muaj qhov khaus rau ntawm daim tawv nqaij. , muaj kev nyab xeeb siab hauv kev siv, thiab muaj kev nqus ultraviolet siab rau thaj tsam UVB, tuaj yeem tiv thaiv 280-330mm ultraviolet rays, thiab muaj qhov nqus tau siab.Nws yog;nws tuaj yeem tiv thaiv tawv nqaij liab thiab sunburn.Tam sim no, cov khoom siv raw no tau siv dav hauv ntau cov tshuaj pleev thaiv hnub pleev xim hauv ntau lub teb chaws.Nws tau txais los ntawm cov tshuaj tiv thaiv ntawm p-Methoxybenzaldehyde thiab Malonic Acid.

Kev npaj:

4-Methoxycinnamic Acid synthesis: Hauv 25-mL, puag ncig hauv qab lub khob, 4-Methoxybenzaldehyde (0.804 mL, 6.61 mmol) (3), Malonic Acid (1.75 g, 16.8 mmol), thiab β-Alanine (0.10 mmol, 1. ) tau yaj hauv pyridine (3.0 mL, 37.1 mmol) thiab rhuab hauv qab reflux rau 90 feeb.Tom qab txias rau hauv chav tsev kub, cov tshuaj tiv thaiv sib tov tau muab tso rau hauv ib da dej dej khov thiab 8.0 mL ntawm concentrated HCl tau maj mam ntxiv.Lub resulting dawb precipitate tau sau los ntawm lub tshuab nqus tsev pom, ntxuav nrog dej txias (2 x 10mL) thiab qhuav kom huv si.Cov khoom raug recrystallized los ntawm cov ethanol (~ 20 mL).
