Zakuthupi ndi Zamankhwala Chemical katundu 3-ethoxy-1,2-propanediol (3-ethoxy-1,2-propanediol), ndi lalifupi unyolo aliphatic etha zosungunulira wa glycerol, viscous, khola madzi mayamwidwe madzi, colorless ndi fungo, misscible ndi madzi. , Mowa ndi zosiyanasiyana zosungunulira organic.
Gwiritsani ntchito Ntchito 3-ethoxy -1, 2-propanediol ndi yofunika wapakatikati kwa synthesis wa dioxolane mankhwala. Mankhwala a Dioxolane ndi mankhwala othandiza kwambiri, omwe amatha kusakanikirana ndi dizilo ngati mafuta. Dioxolane mankhwala munali 6-8 maatomu mpweya ndi zabwino makutidwe ndi okosijeni zosakaniza, ndi kusanganikirana ndi dizilo mafuta kungakhale Kwambiri kuchepetsa mpweya wa olimba particles ndi NOx chifukwa cha kuyaka dizilo.

Mawu Oyamba

3-ethoxy-1,2-propanediol ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha chinthucho:

 

Ubwino:

- Maonekedwe: 3-Ethoxy-1,2-propanediol ndi madzi opanda mtundu mpaka kuwala achikasu.

- Kusungunuka: Kusungunuka m'madzi ndi zosungunulira zambiri, monga ma alcohols ndi ethers.

 

Gwiritsani ntchito:

- 3-ethoxy-1,2-propanediol amagwiritsidwa ntchito ngati zosungunulira komanso zapakatikati.

- Chifukwa cha kusungunuka kwake komanso kukhazikika kwake, amagwiritsidwanso ntchito kwambiri pokonza utoto ndi ma emulsions.

 

Njira:

Kaphatikizidwe wa 3-ethoxy-1,2-propanediol akhoza kuchitidwa ndi njira zotsatirazi:

- 1,2-Propanediol imakhudzidwa ndi chloroethanol.

- Kuchita kwa 1,2-propanediol ndi ether yotsatiridwa ndi esterification.

 

Zambiri Zachitetezo:

- Mukakhudza khungu kapena maso, muzimutsuka nthawi yomweyo ndi madzi ambiri.

- Iyenera kusungidwa m'chidebe chotchinga mpweya, kutali ndi kuyatsa ndi okosijeni, kupewa ngozi ya moto ndi kuphulika.

- Tsatirani machitidwe abwino a labotale ndi kuvala zida zodzitetezera zoyenera mukamagwiritsa ntchito.
