Inkcazo emfutshane:

I-Dietyyl Maloni ngumbala ongenabala kakhulu ulwelo olu-tyheli olune-odor yesiqhamo. Yinto i-diester kwaye isetyenziswa rhoqo kwi-ornthesic synthesis. I-compleund inefomula ye-molecula14o4o4o4 kwaye yaziwa ngeebhloko zayo zokwakha eziguquguqukayo kwi-synthesis yeentlobo ezahlukeneyo zezinto ezahlukeneyo zezinto eziphilayo. I-Diethyl ecocekileyo ye-masokati ihlala icacile kwaye incinci i-viscous.

I-Diethyl Maloni inyibilikisi kwiinyibiliki ezifana ne-ethanol, i-ether, kunye ne-chloroform. Ngenxa ye-hydrophobicty yeqela le-alkyl, isomeleza sayo emanzini silinganiselwe, kodwa isenokuchithwa ukuya kuthi ga kwinqanaba elithile. Ihlala inyibilika kakuhle kwi-non-polar okanye i-swerly porleds porles.

Ukugcinwa

1. Gcina kwindawo epholileyo yendawo epholileyo. Hlala kude nomlilo nobushushu. Ifanele igcinwe ngokwahlukeneyo kwii-oxidants, i-alkalis eyomeleleyo, kunye nokunciphisa iiarhente, kwaye zithintele ukugcinwa okuxubeneyo. Ixhotywe ngeendlela ezahlukeneyo kunye nenani lezixhobo zomlilo. Indawo yogcino kufuneka ixhotywe ngezixhobo zokunyanga ezingxamisekileyo kunye nezixhobo ezifanelekileyo zokugcina.

I-2. Gcina kwaye uthutho ngokungqinelana nemigaqo yeekhemikhali ezinokutsha.

 

I-1. Isikhongozeli: Ivenkile ye-Dietthyl Machanate kwikhonteyina etywiniweyo yokuthintela ungcoliseko kunye nokuphuma. Sebenzisa izikhongozeli ezenziwe ngeglasi okanye kwiplastiki ehambelana.

2. Ubushushu: Nceda uyigcine kwindawo epholileyo neyomileyo, kude nokukhanya kwelanga kunye nemithombo yobushushu. Ngokufanelekileyo, kufuneka igcinwe kubushushu begumbi okanye kwifriji ukuba ukugcinwa kwexesha elide kuyafuneka.

3. Irhasi ye-InErt: Ukuba kunokwenzeka, gcina phantsi kwegesi ye-intert enje nge-nitrogen okanye i-argon ukunciphisa ukubonwa komswakama kunye nomoya, onokubangela i-hydrolysis okanye i-oxidation.

4. Ileyibhile: Ngokucacileyo iileyibheli ngegama leekhemikhali, uxinzelelo kunye nomhla wokugcina ukuqinisekisa ukuchongwa okufanelekileyo nokuphatha.

5. Amanyathelo okhuseleko: Landela zonke izikhokelo zezokhuseleko kunye nemigaqo yokuphatha kunye nokugcina izikhemikhali, kubandakanya ukusetyenziswa kwezixhobo ezifanelekileyo zobuqu (i-PPE) xa uphatha i-Dethyl Mazyli.

 

Phenethyl utywala

Uzinzo

1. Kulumkele ukunxibelelana nee-oxidants, ukunciphisa iiarhente kunye ne-alkalis. Iipropathi zeekhemikhali zizinzile ngakumbi kune-diethyl oxeyalate. Kuba i-hydrolyzed ehamba ngokulula ukuvelisa i-malonic acid, eyi-acidic ngakumbi, kuyimfuneko ukuthintela inhalare yomphunga okanye unxibelelwano ngolusu.

2. Le mveliso inetyhefu esezantsi, i-rat aral ld50> 1600mg / kg, kodwa iya kuba yi-phudrolyzd kwi-acid emzimbeni, kuphephe ukunxibelelana. Hlamba emva konxibelelwano. Abanini zithuthi kufuneka banxibe iigloves zerabha.

Izilumkiso ngexesha lokuhamba
