说明

General description

甲基丙烯醛在300℃下在杂多酸催化剂（主要是 12-钼磷酸）催化下氧化生成甲基丙烯酸。它是异戊二烯氧化的主要产物。

Application

甲基丙烯醛用于研究烃氧化产物和萜烯氧化产物甲基丙烯醛对人眨眼频率的影响，影响水平在十亿分之几。它还用于测定氯原子与丙烯醛、甲基丙烯醛和甲基乙烯基酮反应的速率常数和产物。

Atmospheric fate of methacrolein. 1. Peroxy radical isomerization following addition of OH and O2.

John D Crounse et al.

The journal of physical chemistry. A, 116(24), 5756-5762 (2012-03-29)

Peroxy radicals formed by addition of OH and O(2) to the olefinic carbon atoms in methacrolein react with NO to form methacrolein hydroxy nitrate and hydroxyacetone. We observe that the ratio of these two compounds, however, unexpectedly decreases as the

Effects of methacrolein on the respiratory tract in mice.

S T Larsen et al.

Toxicology letters, 114(1-3), 197-202 (2000-03-14)

The acute respiratory effects of airborne exposure to methacrolein were studied in a recent refinement of the standard test method with mice (ASTM, 1984. American Society for Testing and Materials, Philadelphia). Irritation of the upper respiratory tract caused a concentration-dependent

Computational evaluation of enantioselective Diels-Alder reactions mediated by Corey's cationic oxazaborolidine catalysts.

Michael N Paddon-Row et al.

The Journal of organic chemistry, 74(2), 861-868 (2008-12-11)

The cationic oxazaborolidine-catalyzed Diels-Alder reactions of butadiene and a series of five dienophiles have been studied using density functional theory (B3LYP/6-31G(d)). In each case, the computational results successfully reproduce the experimentally observed sense of stereoinduction and enantiomeric ratio. The computed
