Barta karkarinta ee acetonitrile: halbeeg jireed oo muhiim u ah warshadaha kiimikada
Acetonitrile, sida dareeraha organic ee muhiimka ah ee warshadaha kiimikada, ayaa si weyn loogu isticmaalaa dhinacyada isku-darka daroogada, kiimikooyinka wanaagsan iyo falanqaynta chromatography dareeraha. Hagaajinta cabbirrada jireed ee Acetonitrile ayaa muhiim u ah codsigeeda warshadaha, oo ay ka mid tahay barta karkarinta ay tahay mid ka mid ah cabbirrada ugu muhiimsan. Warqadan, barta karkarinta ee acetonitrile ayaa si faahfaahsan loo falanqeyn doonaa, saameynta halbeeggaan ee hawlgalka kiimikada ayaa laga wada hadli doonaa.
Barta karkarinta ee acetonitrile iyo waxyaabaha saameeya
Meesha karkarinaysa ee acetonitrile caadiyan waa 81.6°C (qiyaastii 179°F), heerkulkuna waxa uu muhiimad wayn u leeyahay kala saarida, hagaajinta iyo farsamooyinka kale ee kala soocida hababka kiimikada. Barta karkarinta ee acetonitrile waxaa saameeya arrimo badan, oo ay ku jiraan cadaadiska, nadiifnimada, iyo isku dhafka walxaha kale. Caadi ahaan, barta karkaraya ee acetonitrile waxay ku xiran tahay cadaadiska jawiga caadiga ah, laakiin haddii cadaadisku isbeddelo, barta karkarinta ayaa sidoo kale isbedeli doonta. Tusaale ahaan, cadaadiska hoos u dhaca, barta karkarinta ee acetonitrile ayaa hoos u dhacda, taas bedelkeeda, xaaladaha cadaadiska, barta karkarinta ayaa kordheysa. Dabeecaddan ayaa ka dhigaysa acetonitrile inay leedahay suurtogalnimo codsi oo ballaadhan iyadoo la raacayo xaalado nidaam oo kala duwan.
Muhiimadda ay leedahay karkarinta acetonitrile ee codsiyada warshadaha
Ogaanshaha barta karkarinta ee acetonitrile waa qiimo tixraac muhiim ah oo loogu talagalay samaynta xaaladaha hawlgalka kiimikada. Wax soo saarka warshadaha, inta badan waa lagama maarmaan in la kala saaro isku-darka, iyo barta karkarinta ee acetonitrile waxay ka dhigaysaa mid ka mid ah walxaha ugu fiican ee habka soo kabashada dareeraha. Tusaale ahaan, falanqaynta chromatography dareeraha ah, barta karkarinta ee ku habboon ee acetonitrile waxay awood u siinaysaa inuumi-baxo heerkul aad u hooseeya, si wax ku ool ah uga fogaato hoos u dhaca kulaylka muunada. Kiimikada synthetic, xakamaynta heerkulka falcelinta ee u dhow ama ka hooseeya barta karkarinta ee acetonitrile waxay caawisaa hubinta badbaadada falcelinta iyo nadiifnimada alaabta.
Sida loo isticmaalo barta karkarinta ee acetonitrile si kor loogu qaado habka wax soo saarka
Aqoonta iyo fahamka barta karkarinta ee acetonitrile, injineeradu waxay wanaajin karaan hababka wax soo saarka si loo hagaajiyo waxtarka iyo dhimista kharashyada. Tusaale ahaan, habka distillation, barta karkaraya ee acetonitrile waxaa loo isticmaali karaa saldhig muhiim ah oo lagu dejiyo heerkulka hawlgalka ee tiirka distillation si loo hubiyo waxtarka kala-soocidda ugu fiican. Adigoo hagaajinaya cadaadiska nidaamka si loo beddelo barta karkarinta ee acetonitrile, waxaa suurtagal ah in lagu gaaro hawlgallo wax-soo-saar badan oo dabacsan oo hoos yimaada xaalado nidaameed oo kala duwan. Habkani kaliya ma badbaadin karo tamarta si wax ku ool ah, laakiin sidoo kale wuxuu hagaajin karaa badbaadada iyo xasilloonida khadka wax soo saarka oo dhan.
Soo koobid
Barta karkarinta ee acetonitrile waa halbeeg jidheed oo muhiim u ah warshadaha kiimikada, kaas oo si toos ah u saameeya naqshadaynta iyo hirgelinta hawlgallada kiimikaad ee kala duwan. Laga soo bilaabo sifooyinka aasaasiga ah ee acetonitrile, faham qoto dheer oo ku saabsan arrimaha saameynta leh ee barta karkarinta iyo doorka ay ku leedahay codsiyada warshadaha waxay ka caawin kartaa injineerada inay si fiican u wanaajiyaan habka wax soo saarka, hagaajinta tayada alaabta iyo inay gaaraan yoolka horumar waara. Iyagoo si buuxda u fahmaya oo isticmaalaya barta karkarinta ee acetonitrile, shirkadaha kiimikadu waxay awoodaan inay ka faa'iidaystaan ​​tartanka suuqa ee ba'an.
