Nhanganyaya
P-hydroxyvalerone inhengo yemubatanidzwa. Iyi inotevera sumo yakadzama kune zvivakwa, mashandisiro, nzira dzekugadzirira uye nekuchengetedza ruzivo rwep-hydroxypenterone:
Hunhu:
P-hydroxyvalerone imvura isina ruvara ine yakasarudzika inonhuhwirira kuravira. Inogona kunyungudutswa nemvura uye akawanda organic solvents akadai ethanol uye ether.
Shandisa:
P-hydroxyvalerone inoshandiswa zvakanyanya muindasitiri yemakemikari. Iyo yakakosha solvent uye inowanzoshandiswa mukugadzirwa kwepende, ingi uye varnishes. P-hydroxypentanone inogona zvakare kushandiswa seyakagadzirwa mbishi zvinhu zvezvinonhuhwirira, senge mapefiyumu uye zvinonhuwirira.
Nzira:
Pane nzira dzakawanda dzekugadzirira p-hydroxypenterone. Imwe yenzira dzinowanzo shandiswa ndeyekuwana p-hydroxypentanone ne acid-catalyzed reaction ye benzoic acid uye acetone. Imwe nzira inowanikwa ne transesterification ye benzoic acid uye acetone, inoteverwa neasidhi hydrolysis.
Zvekuchengetedza
P-hydroxyvalerone imvura inopfuta ine mhute inogona kuumba musanganiswa unobvira kana kuputika nemhepo. Paunenge uchibata nekushandisa, matanho ekudzivirira moto anofanira kutorwa uye kusangana nemoto wakazaruka uye nzvimbo dzepamusoro-soro dzinofanira kudziviswa. P-hydroxyvalerone ine inogumbura uye inoora pameso uye paganda, uye kusangana kwakananga kunofanirwa kudzivirirwa. Midziyo yekuzvidzivirira yakafanira senge magirovhosi nemagirazi zvinofanirwa kupfekwa panguva yekushandiswa.
