Habka wax soo saarka
1. P-chlorobenzoyl chloride waxaa lagu diyaariyey falgalka p-chlorobenzoyl chloride oo ay weheliso anisole, waxaana ku xigay hydrolysis iyo demethylation.
2. Falcelinta p-chlorobenzoyl chloride oo leh phenol: ku milmi 9.4g (0.1mol) oo phenol ah 4ml oo ah 10% xalka sodium hydroxide, ku dar 14ml (0.110mol) oo p-chlorobenzoyl chloride ah oo hoos u dhacaya 40 ~ 45 ℃, ku dar 30 daqiiqo gudahood, oo isla heerkulkaas ku falceli 1 saac. Qabooji heerkulka qolka, shaandhee oo qalaji si aad u hesho 22.3g oo phenyl p-Chlorobenzoate ah. Wax soo saarku waa 96%, barta dhalaalkuna waa 99 ~ 101 ℃.
Daaweynta degdegga ah ee daadinta
Tallaabooyinka ilaalinta, qalabka ilaalinta iyo hababka qashin-qubka degdegga ah ee hawl wadeennada:
Waxaa lagula talinayaa shaqaalaha daaweynta degdegga ah inay xirtaan qalabka neefsashada hawada, dharka ka hortagga joogtada ah iyo galoofyada u adkaysta saliidda caagga ah.
Ha taaban ama ha isku marin daadashada.
Dhammaan qalabka loo isticmaalo inta lagu jiro hawlgalka waa in la dejiyaa.
Inta suurtogalka ah jar isha daadashada. Ka saar dhammaan ilaha dabka.
Aagga digniinta waa in loo qoondeeyaa iyadoo loo eegayo aagga ay saameysay socodka dareeraha, uumiga ama boodhku, shaqaalaha aan khuseynna waa in loo daadgureeyaa aagga badbaadada laga bilaabo dabaysha isgoysyada iyo dabaysha kor u socota.
Tallaabooyinka ilaalinta deegaanka: waxay ka kooban yihiin daadashada si looga fogaado wasakhowga deegaanka. Ka hortag daadashada inay gasho wasakhda, biyaha dusha sare iyo biyaha dhulka hoostiisa.
Hababka kaydinta iyo ka saarista kiimikooyinka daadanaya iyo agabka qashin-qubka ee la isticmaalay:
Daadashada yar: ku ururi dareeraha daadanaya weel xiran intii suurtogal ah. Ku nuug ciid, kaarboon firfircoon ama walxo kale oo aan firfircoonayn oo u wareeji meel ammaan ah. Ha ku shubin bulaacadda.
Daadashada weyn: samee god ama qod god si aad u soo dhaweyso. Xidh tuubada dheecaanka. Xumbo ayaa loo isticmaalaa in lagu daboolo uumiga. Ku wareeji gaariga taangiga ama ururiyaha gaarka ah oo leh bamka aan qarxin karin, dib u warshadeyn ama u qaad goobta daaweynta qashinka si loogu tuuro.
Qalabka ilaalinta shaqsiga:
Ilaalinta neefsashada: marka xoogga hawada ku jira uu ka sarreeyo heerka caadiga ah, xidho maaskaro gaas ah oo shaandho leh (maaskaro badhkeed). Markaad badbaadinayso ama aad ka baxayso xaalad degdeg ah, waa inaad xidhataa qalab neefsasho oo hawada lagu neefsado.
Ilaalinta gacmaha: xidho galoofisyo u adkaysta saliidda caagga ah.
Ilaalinta indhaha: xidho indhaha ilaalinta badbaadada kiimikada.
Ilaalinta maqaarka iyo jirka: xidho dharka shaqada ee ka hortagga sunta.
