Mawu Oyamba
P-hydroxyvalerone ndi organic pawiri. Zotsatirazi ndizofotokozera mwatsatanetsatane za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha p-hydroxypenterone:
Ubwino:
P-hydroxyvalerone ndi madzi opanda mtundu okhala ndi kununkhira kwapadera. Ikhoza kusungunuka ndi madzi ndi zosungunulira zambiri za organic monga ethanol ndi ether.
Gwiritsani ntchito:
P-hydroxyvalerone imagwiritsidwa ntchito kwambiri pamakampani opanga mankhwala. Ndiwosungunulira wofunikira ndipo amagwiritsidwa ntchito kwambiri popanga utoto, inki ndi ma varnish. P-hydroxypentanone itha kugwiritsidwanso ntchito ngati zopangira zopangira zonunkhira, monga zonunkhira ndi zonunkhira.
Njira:
Pali njira zingapo zokonzekera p-hydroxypenterone. Imodzi mwa njira zomwe zimagwiritsidwa ntchito kwambiri ndi kupeza p-hydroxypentanone ndi asidi-catalyzed reaction ya benzoic acid ndi acetone. Njira ina ndi akamagwira transesterification wa asidi benzoic ndi acetone, kenako asidi hydrolysis.
Zambiri Zachitetezo:
P-hydroxyvalerone ndi madzi oyaka omwe nthunzi zake zimatha kupanga zosakaniza zoyaka kapena kuphulika ndi mpweya. Pogwira ndikugwiritsa ntchito, njira zopewera moto ziyenera kuchitidwa ndikukhudzana ndi malawi otseguka komanso magwero otentha kwambiri ayenera kupewedwa. P-hydroxyvalerone imakhala ndi zonyansa komanso zowononga maso ndi khungu, ndipo kukhudzana mwachindunji kuyenera kupewedwa. Zida zodzitetezera zoyenerera monga magolovesi ndi magalasi azivala mukamagwiritsa ntchito.
