disacryln.

Brit.

/dɪˈsakrɪl/,

/dɪˈsakrʌɪl/, U.S.

/dɪˈsækrəl/

Origin: A borrowing from German. Etymon: German Disacryl.

Etymology: < German Disacryl (J. Redtenbacher 1843, in Ann. der Chem. und Pharm. 47 141) < Dis- dis- prefix + Acryl acryl n. Compare later acryl n.In disacryl resin after German Disacrylharz (J. Redtenbacher 1843, in Ann. der Chem. und Pharm. 47 145).

Chemistry.

A white solid formed by the polymerization of acrolein. Also attributive as disacryl resin.

ΚΠ

1843 Chem. Gaz. 1 Dec. 722 Acroleine burns with a bright white flame; it rapidly absorbs oxygen, especially in its aqueous solution, and is converted into white disacryl and acrylic acid.

1855 H. Watts tr. L. Gmelin Hand-bk. Chem. IX. 369 Disacryl-resin [Ger. Disacrylharz]. Once obtained instead of disacryl, from acryl which had been kept for some time, probably because the mass after solidification had been too quickly thrown on the filter and washed.

1864 H. Watts Dict. Chem. II. 336 Acrolein when kept..changes, sometimes..into a resinous matter, disacryl resin. Disacryl is a white, amorphous, tasteless, inodorous powder, which becomes strongly electrical by friction.

1924 Jrnl. Infectious Dis. 35 287 Acrolein..easily becomes polymerized to disacryl or metacrolein.

2010 R. Turkington Chemicals used Illegal Purposes 15/2 Acrolein... Chemical Weapon... Unstable, polymerizes to disacryl, which is a solid.
