Okwu mmalite
P-hydroxyvalerone bụ ngwakọta organic. Ihe na-esonụ bụ nkọwa zuru ezu maka njirimara, ojiji, ụzọ nkwadebe na ozi nchekwa nke p-hydroxypenterone:
Ogo:
P-hydroxyvalerone bụ mmiri mmiri na-enweghị agba nke nwere ụtọ ụtọ pụrụ iche. Enwere ike gbaze ya site na mmiri na ọtụtụ ihe mgbaze organic dị ka ethanol na ether.
Jiri:
A na-eji P-hydroxyvalerone eme ihe n'ọtụtụ ebe na ụlọ ọrụ kemịkalụ. Ọ bụ ihe mgbaze dị mkpa ma na-ejikarị akwadebe agba, inks na varnishes. A pụkwara iji P-hydroxypentanone mee ihe dị ka ihe eji eme ihe na-esi ísì ụtọ, dị ka ihe na-esi ísì ụtọ na ụtọ.
Usoro:
Enwere ọtụtụ ụzọ iji kwadebe p-hydroxypenterone. Otu n'ime ụzọ a na-ejikarị eme ihe bụ ịnweta p-hydroxypentanone site na mmeghachi omume acid-catalyzed nke benzoic acid na acetone. A na-enweta usoro ọzọ site na transesterification nke benzoic acid na acetone, na-esote acid hydrolysis.
Ozi nchekwa:
P-hydroxyvalerone bụ mmiri na-ere ọkụ nke vapors nwere ike ịmepụta ngwakọta ọkụ ma ọ bụ ihe mgbawa na ikuku. Mgbe a na-ejikwa ma na-eji ya, ekwesịrị ịme ihe mgbochi ọkụ ma zere kọntaktị na ọkụ na-emeghe na ebe okpomọkụ dị elu kwesịrị izere. P-hydroxyvalerone nwere mmetụta na-akpasu iwe ma na-emebi emebi na anya na akpụkpọ ahụ, a ga-ezere kọntaktị ozugbo. Ekwesịrị iyi akụrụngwa nchekwa kwesịrị ekwesị dị ka uwe aka na enyo enyo mgbe ejiri ya.
