CINNAMALDEHYDE reacts with sodium hydroxide owing to aerobic oxidation. 00 mL/1. To characterize the synthesized product using its boiling point, results of simple chemical tests and derivatization reactions, along with the determination of the elting points of the hydrazones and comparison of the hydrazones using their RGB values.
Refluxing intimately mixes substances by increasing the contact between the reactant particles through boiling and evaporation, followed by the condensation in the reflux condenser (due to the removal of heat by the cold water flowing in the condenser) and restoration of the synthesized compound and the little (expected) amount of the unreacted reagents on their original vessel (Mayo, Pike and Forbes, 2001). Thus, benzaldehyde, which can remain as it is in sodium hydroxide, was put in first until the formation and attack of the nucleophile, which was formed right after acetaldehyde was dropped into the reaction mixture. 4 Spectral Information Expand this section.
The observed decomposition can be attributed to the instability of cinnamaldehyde, usually denoted by thickening and decomposition, when exposed for a long time to air at elevated temperatures but lower than its boiling point (>70°C) (Gholivand and Ahmadi, 2008).

Cinnamaldehyde inhibits pro-inflammatory cytokines secretion from monocytes/macrophages through suppression of intracellular signaling. Derivatization with 2, 4-dinitrophenylhydrazine was performed by dissolving the test compound (cinnamaldehyde, acetaldehyde and benzaldehyde) in 4. It has been proven that cinnamaldehyde from cinnamon oil has a very high potential in the pharmaceutical industry, aside from its well known role in the food preparation, specifically as spice, odorant and colorant. Incompatible with strong oxidizing agents, strong bases.

Deviations from theoretical melting point values of the two other hydrazones were observed on the experimental melting points gathered. In SWIM's tests, this LSA+cinnamaldehyde adduct is more potent than LSH or LSA, so adjust the dosage down to 1/2 - 1/3 as much. -caryophyllene, limonene and others), eugenol, cinnamyl acetate, eugenol acetate, cinnamyl alcohol, methyl eugenol, benzaldehyde, benzyl benzoate, cuminaldehyde, monoterpenes (linalool, pinene, phellandrene and cymene), safrole and others (List and Horhammer; Masada; Ravindran qtd. 6% of the theoretical yield which was computed as 3. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation).

Occurring naturally as predominantly the trans (E) isomer, it gives cinnamon its flavor and odor. Your contaminated clothing and absorbent paper should be sealed in a vapor-tight plastic bag for eventual disposal.

6| 174| C75B34| Cinnamaldehyde| Red orange solids| 267. LSA+ cinnamaldehyde should be a very stable adduct because the boiling point of cinnamaldehyde is very high.
SMALL SPILLS AND LEAKAGE: If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION.
Having a flat product would cause the increased torsional strain on the molecule due to the very close distance of the carbonyl group and the benzene ring.
Self-condensation of acetaldehyde was expected to be greatly minimized by the procedure employed and the fact that it is energetically unfavorable, according to Fox and Whitesell (2004). Possible side reactions in the experiment conducted were the self-condensation of acetaldehyde and Canizzarro reaction as previously stated along with the preventive measures exercised to minimize their occurrence. Additional study from authoritative database indicates the boiling point of test chemical as 226.69°C estimated by adapted Stein and Brown method.
