1. Takamaiman alakar dake tsakanin zafin jiki da matsa lamba don distillation na n{1}pentanol
Wurin tafasa na n{0}pentanol (1-pentanol) a matsa lamba na yanayi shine digiri 138, amma ana iya saukar da shi sosai ta hanyar distillation. Bisa ga "Lang's Handbook of Chemistry" (bugu na 16) da bayanan gwaji:
1. A 20 mmHg matsa lamba: tafasar batu ne kamar 68-72 digiri , wanda shi ne saba amfani da injin yanayi a cikin dakin gwaje-gwaje.
2. A matsa lamba 10 mmHg: wurin tafasa yana ƙara raguwa zuwa kusan digiri 55-58.
3. A 50 mmHg matsa lamba: tafasar batu ne kamar 85-90 digiri .
* Tushen Bayanai *: Abubuwan da ke sama sun dogara ne akan daidaitattun bayanan bayanan dukiya da rahotannin adabi. Matsakaicin zafin jiki na iya canzawa ta ± 2 digiri saboda dalilai kamar daidaiton kayan aiki da abun ciki na ƙazanta.
Tsayar da ruwa yana rage matsa lamba na tsarin, yana sauƙaƙa ga ƙwayoyin ruwa don tserewa daga yanayin ruwa kuma su shiga lokacin tururi, ta haka rage ma'aunin tafasa. Don matsakaita{1}}masu kaushi kamar n{2}pentanol, wurin tafasa yana raguwa kusan digiri 10-15 ga kowane ragi na matsa lamba.
II. Mabuɗin Mahimmanci da Ƙarin Ilimi don Ƙarƙashin Ruwa
1. Zaɓin Kayan Aiki: Yi amfani da matsi -zagaye mai jurewa{2}}flask na ƙasa, famfo, da tarkon sanyi don tabbatar da hatimi mai kyau.
2. Kula da zafin jiki: Ana ba da shawarar wanka mai mai don guje wa yawan zafi a cikin gida. A lokacin distillation na ainihi, ya kamata a sanya ma'aunin zafi da sanyio a wurin tururi don ƙarin ingantaccen karatu.
3. Nasihun Tsaro: n -pentanol yana ƙonewa kuma yakamata a kiyaye shi daga tushen wuta. Dumama ba zato ba tsammani a ƙarƙashin rage matsa lamba na iya haifar da tashin hankali, don haka ana iya buƙatar zeolite ko motsin maganadisu.
Ƙaddamar da Aikace-aikace:
- n{1}pentanol ana yawan amfani dashi wajen hada kamshi da shirye-shiryen tsaka-tsakin magunguna. Tsabtace injin na iya inganta tsabtar samfur.
- Idan ana buƙatar ƙarin rarrabuwa na isomers (kamar 2-pentanol), ana iya inganta yanayin ta amfani da ginshiƙi mai ɓarna.
III. Kwatancen Bayanai na Ƙwararru da Tambayoyi gama-gari
Littattafai daban-daban suna ba da rahoton wuraren tafasa daban-daban don n{0}pentanol a ƙarƙashin rage matsi. Misali:
Littafin Jagora na Kimiyyar Kimiyya na CRC ya bayyana shi a matsayin digiri 70 a 20 mmHg;
Index ɗin Merck yana ba da digiri 69.
Wannan bambance-bambancen ya samo asali ne daga hanyoyin aunawa da samfurin tsabta. Ana ba da shawarar daidaitawa ta hanyar ƙaramin gwaji kafin gwaji.
A taƙaice: Yakamata a ƙayyade zafin daɗaɗɗen ruwa na n{0}pentanol dangane da matsa lamba. Ana ba da shawarar zazzabi na kusan digiri 70 a 20 mmHg, kuma yakamata a yi gyare-gyare bisa takamaiman yanayin kayan aiki.
