2, 4- Dihydroxyacetophenone Itilizasyon ak sentèz
Pwopriyete chimik 2, 4-Dihydroxyacetophenone parèt tankou yon jòn-mawon rive wouj-mawon amann cristalline poud. Li dousman dekonpoze nan dlo epi li ka fonn nan alkòl cho, piridin, ak asid acetic glacial. Kontrèman, li prèske ensolubl nan etè, benzèn, ak klowofò. Yon reyaksyon ak klori fè lakòz li adopte yon koulè wouj.
Itilizasyon 2,4-Dihydroxyacetophenone (cas# 89-84-9) se yon konpoze ki itil nan sentèz òganik. Li se tou itilize kòm entèmedyè pou pharmaceutique. Reyaktif pou fè kòm yon solisyon 10% alkòl. Yon koulè wouj jwenn ak iyon ferrik nan solisyon yon ti kras asid: Cooper, Ind. Eng. Chem. Anal. Ed. 9, 334 (1937).
Definisyon ChEBI: 2',4'-dihydroxyacetophenone se yon dihydroxyacetophenone ki se asetofenon ki pote substituants hydroxy nan pozisyon 2' ak 4'. Li gen yon wòl kòm yon metabolit plant. Li se yon manm nan resorcinols ak yon dihydroxyacetophenone.
Preparasyon Preparasyon pa reyaksyon asid acetic sou resorcinol,
ak klori zenk (reaksyon Nencki) (94%)
ak trifluorur bor
ak Amberlite IR-120 (yon résine echanj kasyon, kalite asid sulfonik) (87%)
ak asid polifosfò (63%)
ak 70% asid pèklorik (33%).
Referans sentèz (yo) Journal of American Chemical Society, 70, p. 428, 1948DOI:10.1021/ja01181a521
Pwofil sekirite Modere toksik pa enjèstyon. Efè repwodiktif eksperimantal. Yon irite je grav. Lè li chofe pou dekonpozisyon li emèt lafimen asid ak lafimen enèvan.
Sentèz 2, 4-Dihydroxyacetophenone jwenn pa asetilasyon resorcinol ak asid acetic. Anplis de sa, li ka jwenn tou nan reyaji resorcinol ak chloroacetyl oswa anhydride acetic nan prezans klori zenk.
sib Fosfolipas (egzanp PLA)
