Dimethyl subrate(CAS#1732-09-8)

Mawu Oyamba

Dimethyl octanoate, yokhala ndi formula yamankhwala C10H18O4, yomwe imadziwikanso kuti DOP (Di-n-octyl phthalate), ndi madzi opanda mtundu komanso owonekera. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha dimethyl octanoate:

Ubwino:

- Maonekedwe: Madzi opanda mtundu kapena achikasu.

- Kachulukidwe: 1.014 g/mL pa 25 °C (lit.)

- Malo osungunuka: -1.6°C

- Malo otentha: 268 ° C (kuyatsa)

- Kusungunuka: Dimethyl octanoate imasungunuka mu zosungunulira za organic, monga ma alcohols, ethers ndi aromatics, komanso osasungunuka m'madzi.

Gwiritsani ntchito:

- Dimethyl octanoate imagwiritsidwa ntchito makamaka ngati chowonjezera cha pulasitiki ndipo imagwiritsidwa ntchito kwambiri popanga zinthu zapulasitiki monga polyvinyl chloride (PVC). Ikhoza kuonjezera pulasitiki ndi kusinthasintha kwa mapulasitiki, kupititsa patsogolo kusinthika ndi thupi.

- Dimethyl octanoate imagwiritsidwanso ntchito ngati zosungunulira muzinthu zina zama mankhwala monga zokutira, zomatira, inki, ndi mafuta onunkhira.

Njira:

- Njira yokonzekera ya dimethyl octanoate nthawi zambiri imapezeka ndi esterification reaction pogwiritsa ntchito n-octane ndi phthalic acid ngati zopangira.

Zambiri Zachitetezo:

- Dimethyl octanoate imawonedwa ngati yotetezeka pakagwiritsidwe ntchito wamba.

- Chifukwa chakuchepa kwake, zimapangitsa kuti pakhale chiopsezo chocheperako kapena kukhudzana ndi anthu. Komabe, pa kutentha kwakukulu, utsi wapoizoni ndi mpweya woipa ukhoza kupangidwa.

- Kuwonekera kwanthawi yayitali komanso pafupipafupi kumatha kuwononga thanzi, kungayambitse kukhudzidwa kwa khungu kapena kukwiya, komanso kukwiyitsa kupuma ndi kugaya chakudya.

- Mukamagwiritsa ntchito dimethyl octamate, tsatirani njira zodzitetezera, monga kuvala magolovesi oteteza ndi magalasi, komanso kukhala ndi mpweya wabwino.

- Posunga ndikugwira dimethyl octamate, pewani kukhudzana ndi zozimitsa moto ndipo pewani kusakanikirana ndi zinthu zowopsa monga ma oxidants ndi asidi amphamvu.
