5-Chloro-1-pentyne (inozivikanwawo se chloroacetylene) isanganiswa yeorganic. Heino sumo pfupi yezvivakwa zvayo, mashandisiro, nzira dzekugadzira, uye ruzivo rwekuchengetedza:
nature:
1. Kuonekwa: 5-Chloro-1-Pentyne imvura isina ruvara.
2. Density: Kuwanda kwayo i 0.963 g/mL.
4. Solubility: 5-Chloro-1-Pentyne haigadziriswi mumvura uye ine zvakanaka kunyunguduka mune organic solvents yakadai se ethanol uye dichloromethane.
Chinangwa:
5-Chloro-1-pentyne inonyanya kushandiswa sechinhu chekutanga uye chepakati mune organic synthesis.
2. Inogona kushandiswa kugadzira mishonga yakadai sevinyl chloride, chloroalcohols, carboxylic acids, uye aldehydes.
Kugadzira nzira:
5-Chloro-1-Pentyne inogona kugadzirwa nematanho anotevera:
1. Dissolve 1-pentanol mu sulfuric acid uye wedzera sodium chloride.
2. Zvishoma nezvishoma wedzera concentrated sulfuric acid dropwise kune mhinduro pane yakaderera tembiricha.
3. Pisa musanganiswa wekuita kune tembiricha yakakodzera pasi pemamiriro ekuwedzera yakawandisa concentrated sulfuric acid.
4. Kuwedzera kugadzirisa uye kucheneswa kwechigadzirwa chekuita chinogona kupa 5-chloro-1-pentyne.
Chekuchengetedza ruzivo:
1. 5-Chloro-1-Pentyne isanganiswa inogumbura uye inopisa, uye matanho ekuchengetedza anofanira kutorwa panguva yekushanda.
Paunenge uchishandisa nekubata 5-chloro-1-pentyne, midziyo yekudzivirira yakakodzera senge magirovhosi ekudzivirira, magirazi uye zvipfeko zvekudzivirira zvinofanirwa kupfekwa.
3. 5-Chloro-1-Pentyne inofanira kushandiswa munzvimbo inofefetera zvakanaka kudzivirira kuunganidzwa kwemhute uye kubata nemirazvo yakavhurika kana zvitubu zvekupisa.
4. Tsvina inofanira kuraswa zvakanaka maererano nemirau yakakodzera uye haifanirwe kukandwa mumatsime emvura kana nharaunda.
