Kodi Crotonaldehyde CAS 123-73-9 ndi chiyani?

Crotonaldehyde ndi madzi opanda mtundu, owoneka bwino, oyaka. Pali fungo loziziritsa komanso lokwiyitsa. Ikakhudzana ndi kuwala kapena mpweya, imasanduka madzi achikasu otumbululuka, ndipo nthunzi yake imakhala yamphamvu kwambiri yotulutsa utsi wokhetsa misozi. Easy kupasuka m'madzi, akhoza kusakaniza Mowa, etha, benzene, toluene, palafini, mafuta, etc. mu gawo lililonse.

Kugwiritsa ntchito

Crotonaldehyde ndi mankhwala omwe amagwiritsidwa ntchito kwambiri popanga n-butanal, n-butanol, 2-ethylhexanol, sorbic acid, 3-methoxybutanal, 3-methoxybutanol, butenic acid, quinaldine, maleic anhydride, ndi mankhwala a pyridine. Kuphatikiza apo, zomwe zimachitika pakati pa butenal ndi butadiene zimatha kupanga zida za epoxy resin ndi epoxy plasticizers. Kuchitapo kanthu ndi pentaerythritol kuti mupeze zopangira zosagwira kutentha.
