Decarboxylation

[Kandriera]

Hello!

Is it possible to decarboxylate saturated carboxylic acids at a high temperature (above 400-500+)? 

I found an information that only beta-keto acids can be decarboxylated and some specific reactions using catalyst, but everywhere temperature is around 150-200C. 

However, if acids have been annealed above 500C+, is decarboxylation with an intermediate in the form of carbcation possible? Not only acids, but also other carbonyls?

I think at that temperature everything will be cracked.

A catalyst such as thiamine pyrophosphate can decarboxylate alpha-keto acids.
