KAHIKI: ʻO Quinol dimethacrylate kahi huaora E hiki ke hoʻoheheʻe ʻia i ka wai.Hiki ke hoʻomākaukau ʻia ʻo Quinol dimethacrylate mai 1,4-dihydroxy-2,3,5-trimethylbenzene, aqueous formalin a me methyl methacrylate e like me nā mea hoʻomaka.

Hoʻomākaukau: I loko o kahi pahu aniani 200mL i lako me ka condenser, e hoʻohui i 16.7g (59.1mmolCCM, maʻemaʻe kemika: 93.5%) i loko o ka CCM i hoʻomākaukau ʻia ma luna nei, e hoʻokomo i 16.7g methanol, 3.3g (82.5mmol) o NaOH a me 50 g wai. , a ua hoʻopili ʻia ka hui ʻana i ka hydrolysis o ka ester ma 80 ° C ma lalo o ka lewa hau.E hoʻoulu i hoʻokahi hola me ka hoʻouluʻana.Ua kānana ʻia ka hopena hopena ma ka mahana like no ka wehe ʻana i nā mea hiki ʻole ke hoʻoheheʻe ʻia, a laila hoʻohui ʻia i ka dropwise i kahi hopena ʻakika i loaʻa ma ka hoʻoheheʻe ʻana i 11.7 g (85.9 mmol) o ka pāhare hydrogen sulfate i 50 g wai i hoʻokahi hola.E mālama i ka 80 ° C.i loko o kahi pahu aniani 300 ml i hoʻokomo ʻia me ka condenser.Ma hope o ka pau ʻana o ka mālama ʻana i ka neutralization, ua hoʻomaka koke nā kristal i ka wā i hoʻōki ai ka hoʻoulu ʻana, a ua ʻae ʻia ka hui ʻana e kū.Ua kānana ʻia nā kristal ma 80 ° C, holoi ʻia ʻelua me 50 mL o ka wai, a laila hoʻomaloʻo ʻia ma lalo o ka momi ma 80 ° C.Ua lawe ʻia ka hopena no 24 mau hola e loaʻa ai ka 14.5 g (57.9 mmol) o 6-hydroxy-2,5,7,8-tetramethylbenzo-2-carboxylic acid, quinodimethacrylate (ma hope i kapa ʻia ʻo CCA) (Hana: 98.3%, maʻemaʻe kemika: 99.7%).

Nā Hana Ola: ʻO Trolox kahi analog wai-soluble o ka huaora E me nā waiwai antioxidant ikaika.ʻO Trolox kekahi mea paʻa ikaika o ka pōʻino membrane.

Hoʻohana: He antioxidant i loaʻa mai i ka wai-soluble vitamin E me ka hoʻopale radical manuahi a me ka hana antioxidant.
