What is the reaction between a carboxylic acid and an amine?
The direct reaction of a carboxylic acid with an amine would be expected to be difficult because the basic amine would deprotonate the carboxylic acid to form a highly unreactive carboxylate. However when the ammonium carboxylate salt is heated to a temperature above 100 oC water is driven off and an amide is formed.
What is the role of DCC in the reaction of carboxylic acid and amines to form amides *?
The side product of the reaction is a conjugate base of a urea which deprotonates the amide. Without DCC, the amine deprotonates the carboxylic acid instead of a nucleophilic attack on the C=O. So, DCC has two main functions; 1) getting rid of the acidic proton, 2) converting the oxygen into a good leaving group.
What carboxylic acid is needed for octyl formate?
It is found in oranges, grapefruits, and other citrus products. Octyl acetate can be synthesized by the Fischer esterification of 1-octanol and acetic acid: CH3(CH2)7OH + CH3CO2H → CH3(CH2)7O2CCH3 + H2O.

How do you make an amine to amide?
One of the preferred methods for making amines is through a nucleophilic acyl substitution using an acid chloride and amine to form an amide. The amide is then reduced to the amine during a hydride reduction with LiAlH4.
What is formed when an amine reacts with an acid?
Reaction with acids When reacted with acids, amines donate electrons to form ammonium salts.
Why is DCC used?
DCC is a dehydrating agent for the preparation of amides, ketones, and nitriles. In these reactions, DCC hydrates to form dicyclohexylurea (DCU), a compound that is nearly insoluble in most organic solvents and insoluble in water. DCC can also be used to invert secondary alcohols.
How do you form an octyl formate?
Description. Octyl formate has a fruity odor with a rose-orange note and a bitter flavor that is refreshingly fruity green at low concentrations. May be prepared by esterification of n-octyl alcohol with formic acid; by boiling n-octyl chloride with formamide in the presence of small amounts of HCl.
Is formic acid toxic?
Toxicity. Formic acid is the root cause of methanol toxicity as the build up of partially oxidized methanol (i.e., formic acid) in the body results in acidosis. Both methanol and formic acid are toxic through oral and dermal exposure.
What is the most acidic carboxylic acid?
Carboxylic acids , containing a carboxyl group (-COOH), are the most acidic class of standard organic molecules. Carboxylic acids generally have pK a s in the range of 3 – 5, and therefore are weaker acids than hydronium ion (H 3 O + ), but they are stronger acids than other organic acids , such as alcohols (16 – 20), aldehydes and ketones (18 – 22), alkynes (25), benzene (35) or alkanes (50).
What elements are in a carboxylic acid?
Carboxylic acids Acetic acid (CH 3 COOH) Citric acid (C 6 H 8 O 7) Formic acid (HCOOH) Gluconic acid HOCH 2 – (CHOH) 4 -COOH Lactic acid (CH 3 -CHOH-COOH) Oxalic acid (HOOC-COOH) Tartaric acid (HOOC-CHOH-CHOH-COOH)
What are the reactions of carboxylic acid?
Acid Chlorides react with carboxylic acids to form anhydrides.
What is the example of carboxylic acid?
Some common examples of carboxylic acids include acetic acid (a component of vinegar) and Formic acid. Generally, these organic compounds are referred to by their trivial names, an example of a trivial name for a carboxylic acid is acetic acid (CH3COOH). In the IUPAC nomenclature of these compounds, the suffix “-oic acid” is assigned.
