When amines are subjected to heat, they can undergo thermal degradation, leading to the formation of byproducts such as primary amines and ammonia. Additionally, higher temperatures can promote elimination reactions in amines, resulting in the formation of alkenes.

How are biogenic amines removed?
Biogenic amines are typically removed from foods through processes such as fermentation, heat treatment, and freezing. In certain cases, they can also be reduced by using additives or enzymes that break down the amines. Overall, proper food storage and processing techniques play a key role in managing biogenic amines levels.
Why do amines turn yellow?
Amines can turn yellow due to oxidation or degradation processes, forming colored products. This color change may be more prominent when amines are exposed to air, light, or heat over time. It's important to store amines properly in a dark, cool, and oxygen-free environment to prevent yellowing.
Do amines and nitrates cancel each other in the stomach?
Amines + Nitrates/Nitrites = carcinogenic nitrosamines
Why is diazotization not possible in aliphatic amines?
Diazotization is not possible in aliphatic amines because they lack a reactive aromatic ring needed for the process. Aliphatic amines do not have the required electron density and stability to form diazonium salts. Only aromatic amines can undergo diazotization reaction with nitrous acid.
Is amine dangerous?
Amines are a broad class of organic compounds that vary in their properties and toxicity. Some amines can be hazardous if handled improperly, especially in high concentrations or if they are toxic or corrosive. It is important to follow proper safety precautions when working with amines.

What rock comes after granite Is subjected to enough heat and pressure in the rock cycle?
When granite is subjected to enough heat and pressure, it becomes a metamorphic rock called gneiss.
Do earthquakes happen in Romania?
Yes, Romania is subjected to earthquakes.
What are amines known for in chemistry?
Amines are produced when a hydrogen atom in ammonia has been replaced by an alkyl or aryl group. Examples of amines are biogenic amines, amino acids and aniline.
Who won the battle of Amines?
German's won the battle of amines
What is the formation of slate?
when shale is subjected to heat and pressure, it can be metamorphosed into slate.
Why is aliphatic amines stronger bases than aromatic amines?
Aliphatic amines are stronger bases than aromatic amines because the lone pair on the nitrogen atom in aliphatic amines is more available for donation due to the absence of resonance effects that stabilize the lone pair in aromatic amines. This makes aliphatic amines more likely to accept protons and act as bases.
If shale is subjected to heat and pressure what type of rock dose it form?
a rock
When heated with chloroform secondary amines and tertiary amines are?
Secondary amines produce N-alkyl-substituted formamides, while tertiary amines form N-alkyl-substituted chloroformamides when heated with chloroform.
Do amines contain oxygen?
No, amines do not contain oxygen. Amines are organic compounds that contain a nitrogen atom bonded to hydrogen atoms and/or alkyl or aryl groups.
How marble stone formed?
Marble is formed when limestone is subjected to pressure and great heat.
