'''Arolein''' atau '''propenal''' ialah sebatian [[aldehid]] tak tepu teringkas dengan formula kimia CH<sub>3</sub>CCHO. Sebatian ini merupakan cecair tanpa warna dengan bau yang sengit. Sebatian ini biasanya digunakan sebagai [[biosid]] serta pelopor bagi sebatian-sebatian kimia lain seperti [[metionina]], sejenis [[asid amino]].

== Penghasilan ==
Akrolein dihasilkan dalam industri melalui pengoksidaan [[propena]] dengan [[oksida logam]] sebagai mangkin dalam proses yang melibatkan [[pemangkinan heterogen]].<ref name="Ullmann">{{Ullmann||authors=Dietrich Arntz, Achim Fischer, Mathias Höpp, Sylvia Jacobi, Jörg Sauer, Takashi Ohara, Takahisa Sato, Noboru Shimizu and Helmut Schwind|title=Acrolein and Methacrolein|year=2012|doi=10.1002/14356007.a01_149.pub2}}</ref>

<chem>CH2CHCH3 + O2 -> CH2CHCHO + H2O</chem>

Akrolein juga boleh dihasilkan melalui kondensasi [[formaldehid]] dan [[asetaldehid]].

<chem>HCHO + CH3CHO -> CH2CHCHO + H2O</chem>

Selain itu, sebatian ini boleh dihasilkan dalam persekitaran makmal melalui tindak balas [[kalium bisulfat]] terhadap [[gliserol]].<ref>{{OrgSynth|author1=Homer Adkins|authorlink1=Homer Burton Adkins|author2=W.

== Kesan kesihatan ==
Akrolein merupakan sebatian beracun dan merengsa dengan kuat terhadap kulit, mata dan rongga hidung. Terdapat hubung kait gas akrolein dari asap rokok dengan risiko [[barah peparu]].<ref name="Feng">{{cite journal|last=Feng|first=Z|author2=Hu W|author3=Hu Y|author4=Tang M|date=October 2006|title=Acrolein is a major cigarette-related lung cancer agent: Preferential binding at p53 mutational hotspots and inhibition of DNA repair|url=http://www.pnas.org/cgi/reprint/0607031103v1|journal=[[Proceedings of the National Academy of Sciences]]|volume=103|issue=42|pages=15404–15409|bibcode=2006PNAS..10315404F|doi=10.1073/pnas.0607031103|pmc=1592536|pmid=17030796}}</ref>
