Mawu Oyamba

3,4-Xylenol, yomwe imadziwikanso kuti m-xylenol, ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 3,4-xylenol:

 

Ubwino:

- 3,4-Xylenol ndi madzi opanda mtundu okhala ndi kununkhira kwapadera.

- Ili ndi mphamvu yosungunuka m'madzi ndi zosungunulira zambiri za organic.

- Imawonekera ngati mawonekedwe opingasa a dimer kutentha kutentha.

 

Gwiritsani ntchito:

- Imagwiritsidwa ntchito ngati antibacterial ndi antiseptic pophika mu fungicides ndi preservatives.

- Amagwiritsidwa ntchito ngati chothandizira pakupanga mankhwala.

 

Njira:

- 3,4-Xylenol akhoza kukonzedwa ndi condensation anachita phenol ndi formaldehyde pansi acidic mikhalidwe.

- Pochitapo kanthu, phenol ndi formaldehyde amapangidwa ndi chothandizira kuti apange 3,4-xylenol.

 

Zambiri Zachitetezo:

- 3,4-Xylenol ili ndi kawopsedwe kakang'ono, komabe ndikofunikira kuigwiritsa ntchito mosamala.

- Nthunzi kapena zopopera zimatha kukwiyitsa komanso kuwononga maso ndi khungu.

- Mukamagwira ntchito, gwiritsani ntchito zida zoyenera zodzitetezera, monga magolovesi amankhwala ndi magalasi.

- Posunga ndikugwira 3,4-xylenol, ndikofunikira kuyang'anira bwino zinyalala kuti mupewe kuwononga chilengedwe.
