SELECTIVE OXIDATION OF ALCOHOLS BY K2FeO4-Al2O3-CuSO4*5H2O
Kim, Kwan Soo,Song, Yang Heon,Lee, Nam Ho,Hahn, Chi Sun
, p. 2875 - 2878 (1986)
A solid mixture of K2FeO4, Al2O3 and CuSO4*5H2O efficiently oxidized allylic, benzylic, and saturated secondary alcohols to the corresponding aldehydes or ketones but did not oxidize saturated primary alcohols.

Revisiting the Palladium-Catalyzed Carbonylation of Allyl Alcohol: Mechanistic Insight and Improved Catalytic Efficiency

, p. 1881 - 1886 (2020)
Although crotonic acid (CA) is in high demand due to its use in various industrial applications, the preparation of CA currently requires a multi-step process from the petrochemical cracking of ethane with a very low overall yield and poor selectivity. An atom economical, one-step, carbonylation of readily accessible allyl alcohol to CA is one of the attractive approaches. In this study, the direct carbonylative transformation of allyl alcohol to CA was analyzed in detail to detect the reaction intermediates and propose a reaction mechanism. Following the reaction mechanism, the process was optimized to synthesize CA via the direct carbonylation of allyl alcohol with improved efficiency and productivity (TON = 420) under mild reaction conditions using Pd-based catalytic systems.
SEVERAL MECHANISMS IN THE ELIMINATION KINETICS OF ω-CHLOROCARBOXYLIC ACIDS IN THE GAS PHASE
Chuchani, Gabriel,Martin, Ignacio,Rotinov, Alexandra,Dominguez, Rosa M.,Perez, Milogrados I.
, p. 133 - 138 (1995)
The kinetics of the gas-phase pyrolysis of ω-chlorocarboxylic acids were examined in a seasoned static reaction vessel and in the presence of at least twice the amount of the free radical inhibitor cyclohexene or toluene.In conformity with the available experimental data on rate determination, these reactions proved to be unimolecular and obeyed a first-order rate law.The presence of the primary chlorine leaving group in Cl(CH2)nCOOH (n=1-4) showed a change in mechanism from intramolecular displacement of the Cl leaving group by the acidic hydrogen of the COOH to anchimeric assistance of the carbonyl COOH to the C-Cl bond polarization in the transition state.This mechanistic consideration is nearly the same for the series of 2-, 3-, and 4-chlorobutyric acids.The chlorine atom at the 2-position of acetic, propionic and butyric acids is dehydrochlorinated through a prevailing reaction path involving a polar five-membered cyclic transition state.
Straightforward Synthesis of 2-Alkenoic Acids from the Corresponding Saturated Aldehydes
Outurquin, Francis,Paulmier, Claude
, p. 690 - 691 (1989)
2-Alkenoic acids may be prepared in good yields from saturated aldehydes via α-selenenylation with 4-(phenylseleno)morpholine formed in situ, followed by hydrogen peroxide oxidation.The actual oxidizing agent is benzeneperseleninic acid which is formed in the reaction medium.
Effect of the Reaction Products on the Rate of Oxidation of Crotonaldehyde
Fedevich,Levush,Fedevich,Kit
, p. 29 - 32 (2003)
Study of the oxidation of crotonaldehyde revealed an appreciable inhibitory effect of the products on the process. Analysis of the kinetic data obtained over a wide range of reaction conditions (c0 1.5-3.3 M, pO2 1-16 atm, T 293-309 K) showed that the overall oxidation process (with account taken of the inhibitory effect of the products) is described by the equation: WCA = kap* CCA (pO2 )°1.6 (1 + 0.17 Δ cCA τ)-1, where Kap* is the apparent rate constant, and Δ cCAτ is the decrease of the aldehyde concentration by a moment τ.

Paragraph 0261-0265, (2019/01/15)
The present invention is directed to reactor systems and processes for producing acrylonitrile and acrylonitrile derivatives. In preferred embodiments of the present invention, the processes comprise the following steps: introducing an epoxide reagent and carbon monoxide reagent to at least one reaction vessel through at least one feed stream inlet; contacting the epoxide reagent and carbon monoxide reagent with a carbonylation catalyst to produce a beta-lactone intermediate; polymerizing the beta-lactone intermediate with an initiator in the presence of a metal cation to produce a polylactone product; heating the polylactone product under thermolysis conditions to produce an organic acid product; optionally esterifying the organic acid product to produce one or more ester products; and reacting the organic acid product and/or ester product with an ammonia reagent under ammoxidation conditions to produce an acrylonitrile product.
