1 propanol and benzoic acid properties
If, instead of the hydrochloride, the free base is desired, it is readily prepared bydissolving or suspending the hydrochloride in a small volume of alcohol, diluting with water and treating with an excess of sodium carbonate. Among the benzoic and p-amino benzoic esters of alicyclic amino alcohols which are included in the invention and have valuable properties for local anesthetic uses are the esters oi the following: 1-cyclohexylaminopropanol 1- i-methylcyclohexyl -aminopropanol 2-cyclohexylaminobutanol 2-cyclohexylaminomethyl-l-propanol 1-cyclohexylaminomethylpropanol 3-cyclohexylaminopropanol 2-cyclohexylaminopropanol l-cyclopentylamino-Z-propanol 1- 3-ethylcyclopentyl aminopropanol 1- i-ethylcyclohexyl amino-Z-propanol 1-cyclopentylaminomethylpropanol 2-cyclopentylaminomethylpropanol 2-cyclopentylaminobutanol 2- -i-methylcyclohexyl amino-l-butanol 3-cyclopentylaminopropanol 2-cyclopentylamino-l-propanol and others in which the alcohol radical has three or four carbon atoms and the alicyclic group not more than ten. The layers are separated and the aqueous layer is extracted once with methylene chloride. When reduction is complete, the catalyst is removed by filtration in an atmosphere of carbon dioxide and the filtrate concentrated to dryness in a vacuum. Some esters can be prepared by esterificationa reaction in which a carboxylic acid and an alcohol, heated in the presence of a mineral acid catalyst, form an ester and water:. These new anesthetics may be used by infiltration or injection or for surface anesthesia, for example, for application to the eye. Concept Review Exercises From what carboxylic acid and what alcohol can the ester isopropyl nonanoate be made? If the nitro compound is reduced as a salt which through its acidic reaction would attack base metal catalysts such as nickel or copper chromite, noble metal catalysts are used. The new anesthetics are amines, that is, bases, and will ordinarily be used in the form of salts, for example, as a hydrochloride, sulfate, sulfamate, tartrate, glycolate or other salt, as the free bases themselves are quite insoluble in water.

Propyl benzoate has a nutty odor and sweet fruity or nut-like taste, and as such, it is used as a synthetic flavoring agent in foods. It also has antimicrobial properties and is used as a preservative in cosmetics. n-propyl benzoate, benzoic acid propyl ester. 5 days ago Propyl benzoate | C10H12O2 | CID - structure, chemical names, Molecular Formula: C10H12O2 Benzoic acid n-propyl ester.

It is also formed into films called Mylar. When magnetically coated, Mylar tape is used in audio- and videocassettes. If another benzoyl halide, for example, a bromide is used, or if the corresponding anhydride is used, other salts of the amino alcohol than the hydrochloride may be used.
Further, if the benzoate or p-amino benzoate is produced in the form of a salt with any given acid, it is readily converted to the salt of some other acid, by treatment with alkali to liberate the free base and subsequent neutralization with the desired acid.

New alpha-amino-beta-hydroxycarboxylic acid amides and a process of preparing them.
It will be noted that these compounds are secondary amines, that is, the amino group of the alicyclic amino alcohol residue is a secondary amino group, two of the hydrogens of ammonia having been replaced. The residue is dried by adding benzene and again distilling to dryness in vacuum and recrystallized from methyl ethyl ketone. The layers are separated and the aqueous layer is extracted once with methylene chloride. The free base which is liberated is extracted with benzene. USA en. Example I. |

Because of the convenience of purification and availability of the intermediates, the compounds will ordinarily be prepared by condensing benzoyl or p-nitro benzoyl chloride with the hydrochloride of the alicyclic amino alcohol, and the benzoyl or nitro benzoyl ester produced in the form of the hydrochloride.

A knitted polyester tube, which is biologically inert, can be used in surgery to repair or replace diseased sections of blood vessels.
If another benzoyl halide, for example, a bromide is used, or if the corresponding anhydride is used, other salts of the amino alcohol than the hydrochloride may be used.

I claim: 1. Henry et al. The conversion of the salt of the benzoate or p-amino benzoate with one acid to the salt with another acid, or to the free base, or the neutralization of the free base to form salts, involve procedures which are well known to those skilled in the art and require no detailed description herein.

Write the equation for the reaction of benzoic acid with each compound.
The benzoic acid esters are prepared by reaction of benzoyl chloride or other halide or anhydride with a salt of the alicyclic amino alcohol. Video: 1 propanol and benzoic acid properties methanol and benzoic acid reflux SUA3 en. Further condensation reactions then occur, producing polyester polymers. The alicyclic amino alcohols used as salts for the production of the new compounds are advantageously prepared by condensing the cor- 2 responding ketone with the corresponding amino alcohol and reducing. The invention will be further illustrated by the following specific examples, but it is not limited thereto, Example I. Esters are made by the reaction of a carboxylic acid with an alcohol, a process that is called esterification. |
