Habka wax soo saarka
1. P-chlorobenzoyl chloride waxaa lagu diyaariyey falcelinta p-chlorobenzoyl chloride leh ansole, oo ay ku xigto hydrolysis iyo demethylation.
2. Reaction of p-chlorobenzoyl chloride with phenol: milmi 9.4g (0.1mol) of phenol in 4ml of 10% sodium hydroxide solution, ku dar 14ml (0.110mol) of p-chlorobenzoyl chloride dropwise at 40 ~ 45 it in 40 ~ 45 ℃ 30min, oo ka fal celi isla heerkul 1H Ku qabooji heerkulka qolka, shaandhee oo engeji si aad u hesho 22.3g ee phenyl p-Chlorobenzoate. Wax-soo-saarku waa 96%, barta dhalaaliduna waa 99 ~ 101 ℃.
Daawaynta degdega ah ee daadinta
Tallaabooyinka ilaalinta, qalabka ilaalinta iyo habraacyada qashin-qubka degdegga ah ee hawl-wadeennada:
Waxaa lagu talinayaa in shaqaalaha daawaynta degdega ah ay xidhaan qalabka neefsashada ee hawada, dharka lidka ku ah joogsiga iyo galoofyada u adkaysta saliida caagga ah.
Ha taaban oo ha dhaafin wax daadinta.
Dhammaan qalabka la isticmaalo inta lagu jiro hawlgalka waa in dhulka la dhigo.
Iska jar isha daadinta inta ugu badan ee suurtogalka ah. Tirtir dhammaan ilaha dabka
Aagga digniinta waa in loo qoondeeyaa iyadoo loo eegayo aagga ay saameeyeen qulqulka dareeraha, uumiga ama siigada faafinta, iyo shaqaalaha aan khusayn waa in laga daadgureeyaa aagga badbaadada ee dabaylaha is-tallaabaya iyo kor u kaca.
Tallaabooyinka ilaalinta deegaanka: waxay ka kooban yihiin dareere si looga fogaado wasakhowga deegaanka. Ka ilaali daadinta inay soo gasho bulaacadaha, biyaha sare iyo biyaha dhulka hoostiisa.
Hababka kaydinta iyo ka saarista kiimikooyinka soo daatay iyo alaabta la tuuro ee la isticmaalo:
Diidista yar: ku ururi dareeraha dareeraha weel la dabooli karo ilaa inta suurtogalka ah. Ku nuugo ciid, kaarboon firfircoon ama walxo kale oo aan shaqayn oo u gudbi meel nabdoon. Ha ku daadin bulaacada.
Diidmo badan: dhis biyo ama god qodo soo dhawaynta. Xir tuubada dheecaanka qaada. Xumbada waxaa loo isticmaalaa in lagu daboolo uumiga. Ku wareeji baabuurka taangiga ama ururiyaha khaaska ah oo wata bamka aan qarxin karin, dib u warshadaynta ama u qaadida goobta daaweynta qashinka si loo tuuro.
Qalabka ilaalinta shakhsi ahaaneed:
Ilaalinta neefsashada: marka xooga saarida hawadu ay dhaafto heerka caadiga ah, xidho maaskaro gaaska shaandhaysa (maaskaro badh). Markaad badbaadinayso ama daad guraynayso xaalad degdeg ah, waa inaad xidhataa qalabka neefsashada.
Ilaalinta gacanta: xidho galoofyada saliida caagga ah.
Ilaalinta indhaha: xidho indhaha ilaalinta badbaadada kiimikada.
Ilaalinta maqaarka iyo jidhka: xidho dharka shaqada ee sunta ka hortagta.
