Monomethyl dodecanedioate(CAS#3903-40-0)

Mawu Oyamba

Monomethyl dodecanedioate, yemwenso amadziwika kuti octylcyclohexylmethyl ester, ndi organic pawiri.

Ubwino:

- Maonekedwe: Monomethyl dodecanedioate imapezeka ngati madzi opanda mtundu.

- Kusungunuka: Kusungunuka mu zosungunulira organic monga ma alcohols, ethers, ndi ketones.

- Poyatsira: Pafupifupi 127°C.

Gwiritsani ntchito:

- Monomethyl dodecanedioate ndi mankhwala ofunika kwambiri, omwe nthawi zambiri amagwiritsidwa ntchito pokonzekera mafuta opangira ntchito komanso mafuta odzola kwambiri.

- Itha kugwiritsidwanso ntchito ngati plasticizer ya mapulasitiki ndi mphira, kukulitsa kusinthasintha kwawo komanso kusinthika.

- Monomethyl dodecanedioate itha kugwiritsidwanso ntchito ngati zopangira zopangira organic, monga kukonza utoto, ma fulorosenti, osungunula ndi mapulasitiki.

Njira:

Kukonzekera kwa monomethyl dodecanedioate nthawi zambiri kumachitika ndi izi:

1. Onjezani dodecanedioic acid ndi methanol ku riyakitala.

2. Zochita za esterification pa kutentha koyenera ndi kupanikizika nthawi zambiri zimafuna kukhalapo kwa chothandizira monga sulfuric acid kapena hydrochloric acid.

3. Pambuyo pomaliza, mankhwalawa amasiyanitsidwa ndikuyeretsedwa ndi kusefera kapena distillation.

Zambiri Zachitetezo:

- Pewani kutulutsa mpweya, kukhudza khungu ndi maso. Zida zodzitetezera zoyenerera monga magolovesi, magalasi otetezera, ndi zovala zodzitetezera ziyenera kuvalidwa panthawi yogwira ntchito.

- Pewani kukhudzana ndi ma oxidizing amphamvu panthawi yosungira ndi mayendedwe kuti mupewe moto ndi kuphulika.

- Pogwira ndi kutaya zinyalala, tsatirani malamulo ndi malamulo a mderalo, ndikutaya zinyalala moyenerera.
