Daim ntawv thov

Crotonaldehyde yog cov khoom siv hluavtaws uas nquag siv rau kev tsim cov n-butanal, n-butanol, 2-ethylhexanol, sorbic acid, 3-methoxybutanal, 3-methoxybutanol, butenic acid, quinaldine, maleic anhydride, thiab pyridine khoom. Tsis tas li ntawd, cov tshuaj tiv thaiv ntawm butenal thiab butadiene tuaj yeem tsim epoxy resin raw khoom thiab epoxy plasticizers. Reacting nrog pentaerythritol kom tau txais cov khoom kub-resistant resin raw khoom.
