Ko te Roopu Whakamate
Trans-4-Methoxycinnamic Acid (CAS: 943-89-5), Ko nga Esters i ahu mai i te waikawa trans-4-methoxycinnamic he kaihoroi whai hua o te hihi UV.Mahi i roto i te whakahiato waro o takawaenga ho'oraa, synthetic taero anti-adrenergic esmolol, poke ultraviolet absorption.Ka whakamahia ano hei reagent matū.
I tenei wa, ko te 4-Methoxycinnamic Acid Acid hei whakamaarama i te ra ko te p-Methoxycinnamate octyl, he wai kowhai kowhai marama ranei, he kore e rewa i roto i te wai, he wairewa i roto i nga whakarewa pararopi penei i te ethanol me te ethyl acetate, Kaore he riri ki te kiri. , he nui te haumaru i roto i te whakamahinga, he nui te tere o te whakauru ultraviolet mo te waahi o te UVB, ka taea te aukati i nga hihi ultraviolet 280-330mm, me te tere o te whakauru.Ko te;ka taea te aukati i te whero o te kiri me te wera o te ra.I tenei wa, kei te whakamahia nuitia tenei rauemi mata ki te maha o nga mea whakapaipai parepare i nga whenua rereke.Ka whiwhihia e te tauhohenga o te p-Methoxybenzaldehyde me te Malonic Acid.
4-Methoxycinnamic Acid Synthesis: I roto i te 25-mL, porotaka i raro i te ipu, 4-Methoxybenzaldehyde (0.804 mL, 6.61 mmol) (3), Malonic Acid (1.75 g, 16.8 mmol), me te β-Alanine (0.12 g, 1.10 mmol). ) ka rewa ki te pyridine (3.0 mL, 37.1 mmol) ka whakamahana i raro i te reflux mo te 90 meneti.Whai muri i te whakamatao ki te pāmahana rūma, ka makahia te ranunga tauhohenga ki roto i te pati hukapapa me te 8.0 mL o te HCl kukū ka āta tāpirihia.I kohia te rerenga ma ma te filtration korehau, ka horoia ki te wai matao (2 x 10mL) ka whakamaroke rawa.I rerystallized te hua mai i te ewaro tino (~20 mL).
