I-Monomethyl dodecanedioate(CAS#3903-40-0)

Intshayelelo

I-Monomethyl dodecanedioate, eyaziwa ngokuba yi-octylcyclohexylmethyl ester, yikhompawundi ephilayo.

Umgangatho:

- Imbonakalo: I-Monomethyl dodecanedioate iqhele ukufunyanwa njengolwelo olungenambala.

-Ukunyibilika: Inyibilika kwizinyibilikisi zendalo ezifana neealkoholi, ii-ethers, kunye neeketones.

- Indawo yokuQala: Malunga ne-127°C.

Sebenzisa:

- I-Monomethyl dodecanedioate yimathiriyeli ebalulekileyo yekhemikhali ekrwada, ehlala isetyenziswa ekulungiseleleni izithambisi eziphezulu zokusebenza kunye nezithambiso eziphezulu.

- Inokusetyenziswa kwakhona njenge-plasticizer yeeplastiki kunye nerabha, ukuphucula ukuguquguquka kunye nokuqhubekeka.

- I-Monomethyl dodecanedioate ingasetyenziselwa njengezinto eziluhlaza kwi-organic synthesis, ezifana nokulungisa idayi, i-fluorescents, i-agent enyibilikayo kunye neeplastiki.

Indlela:

Ukulungiswa kwe-monomethyl dodecanedioate ngokuqhelekileyo kuqhutyelwa ngamanyathelo alandelayo:

1. Yongeza i-dodecanedioic acid kunye ne-methanol kwi-reactor.

2. Iimpendulo ze-Esterification kwiqondo lokushisa elifanelekileyo kunye noxinzelelo zidla ngokufuna ubukho be-catalyst efana ne-sulfuric acid okanye i-hydrochloric acid.

3. Emva kokuphela kokuphendula, imveliso iyahlukana kwaye ihlanjululwe ngokucoca okanye i-distillation.

Ulwazi ngoKhuseleko:

- Kuphephe ukuphefumla, ukudibana nolusu namehlo. Izixhobo ezifanelekileyo zokukhusela ezinjengeeglavu, iiglasi zokukhusela, kunye nempahla yokukhusela kufuneka zinxitywe ngexesha lokusebenza.

- Gwema ukunxibelelana neearhente ezinamandla ze-oxidizing ngexesha lokugcinwa kunye nokuthutha ukuphepha umlilo kunye nokuqhuma.

- Xa uphethe kwaye ulahla inkunkuma, thobela imithetho yengingqi kunye nemimiselo efanelekileyo, kwaye ulahle inkunkuma ngokufanelekileyo.
