I-Dimethyl subrate(CAS#1732-09-8)

Intshayelelo

I-Dimethyl octanoate, kunye ne-chemical formula C10H18O4, eyaziwa ngokuba yi-DOP (i-Di-n-octyl phthalate), i-liquid engenambala kunye ne-transparent. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-dimethyl octanoate:

Umgangatho:

- Imbonakalo: Ulwelo olungenambala okanye olutyheli.

- Ubuninzi: 1.014 g/mL ku-25 °C (lit.)

Indawo yokunyibilika: -1.6°C

Indawo yokuBilisa: 268 °C (lit.)

- I-Solubility: I-Dimethyl octanoate i-soluble kwi-solvents eziphilayo, ezifana ne-alcohol, i-ethers kunye ne-aromatics, kwaye ayinyibiliki emanzini.

Sebenzisa:

- I-Dimethyl octanoate isetyenziswa kakhulu njengezongezelelo zeplastiki kwaye isetyenziswa ngokubanzi kwimveliso yeeplastiki ezifana ne-polyvinyl chloride (PVC). Inokunyusa iplastiki kunye nokuguquguquka kweeplastiki, ukuphucula ukuqhutyelwa phambili kunye neempawu zomzimba.

- I-Dimethyl octanoate isetyenziswa ngokuqhelekileyo njenge-solvent kwezinye iimveliso zeekhemikhali ezifana neengubo, i-adhesives, i-inki kunye neziqholo.

Indlela:

- Indlela yokulungiselela i-dimethyl octanoate idla ngokufunyanwa nge-esterification reaction usebenzisa i-n-octane kunye ne-phthalic acid njengezinto eziluhlaza.

Ulwazi ngoKhuseleko:

- I-Dimethyl octanoate ithathwa njengekhuselekile phantsi kweemeko eziqhelekileyo zokusetyenziswa.

- Ngenxa yokuguquguquka okuphantsi, ibeka umngcipheko omncinci wokuphefumla okanye ukuvezwa ebantwini. Nangona kunjalo, kumaqondo obushushu aphezulu, umsi oyityhefu kunye neegesi eziyingozi zinokuveliswa.

- Ukubonakaliswa kwexesha elide kunye nexesha elide kunokuba yingozi kwimpilo, kunokubangela uvakalelo lwesikhumba okanye ukucaphuka, kwaye kunokucaphukisa inkqubo yokuphefumula kunye neyokugaya.

- Xa usebenzisa i-dimethyl octamate, thatha amanyathelo okhuseleko ayimfuneko, afana nokunxiba iiglavu zokukhusela kunye neeglasi, kunye nokugcina umoya omhle.

- Xa ugcina kwaye uphethe i-dimethyl octamate, kunqande ukudibana nemithombo yomlilo kwaye ugweme ukuxubana nempahla eyingozi efana ne-oxidants kunye neeasidi ezinamandla.
