Nhanganyaya
6-Chloronicotinaldehyde (inozivikanwawo se2,4,6-chlorobenzoic acid aldehyde) inhengo yehupenyu. Iyi inotevera sumo yezvivakwa, mashandisiro, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye6-chloronicotinaldehyde:
Properties: 6-Chloronicotinaldehyde ikristaro isina ruvara kana chena crystalline poda ine hwema hunonhuwa. Iine kupokana kuri pakati nepakati uye inogona kunyungudika mune zvakawanda organic solvents senge madoro, ether, uye ketoni. Iyo inenge isinganyungudike mumvura asi inogona kunyungudutswa muorganic solvents.
Zvishandiso: 6-Chloronicotinaldehyde inowanzoshandiswa se reagent uye yepakati mune organic synthesis. Inoshandiswa sechinhu chakabikwa chemishonga yezvipembenene, mishonga yesora, uye fungicides muchikamu chekurima.
Kugadzirira nzira: 6-chloronicotinaldehyde inogona kuwanikwa nekuita kwe benzoyl chloride uye aluminium chloride. Maitiro ekugadzirisa anogona kuitwa pane tembiricha yekamuri. Iyo chaiyo synthesis nzira ndeyotevera:
C6H5COCl + AlCl3 -> C6H4ClCOCl + HCl
C6H4ClCOCl + HCl -> C7H3Cl3O + CO2 + HCl
Ruzivo rwekuchengetedza: 6-Chloronicotinaldehyde inotsamwisa, dzivisa kusangana neganda nemeso. Matanho akakodzera ekuzvidzivirira anofanira kutorwa pakushandisa, akadai sekupfeka magirovhosi, zvipfeko zvemaziso zvinodzivirira, uye masks ekudzivirira. Dzivisa kufema mhute yayo kana huruva panguva yekushanda. Paunenge uchichengeta nekubata 6-chloronicotinal, tevera akakodzera maitiro ekushanda akachengeteka uye uchengetedze zvakachengeteka mumudziyo wakatarwa. Pakurasa tsvina, inofanira kuraswa zvakakodzera maererano nemitemo yenzvimbo.
