US Amines HOME ABOUT PICTORIAL IMPRESSIONS PRODUCT INFO TECHNICAL INFO SALES CONTACT SAFETY NOTES Safety Notes As the liquid alkylamines are strong, lipidsoluble bases, they are corrosive to the skin and mucous membranes, and therefore it is imperative to avoid contact with these. Amine vapors, if inhaled, cause inflammation of the respiratory organs. Even in low concentrations amine vapors cause damage to the conjunctiva. The maximum workplace concentrations of the low boiling amines are approximately the same as the value for ammonia. In view of these physiological properties alkylamines must be regarded as dangerous substances as defined in the German regulations on dangerous substances. When alkylamines are handled, protective clothing, gloves and close-fitting goggles must be worn. Splashes on the skin must be washed off immediately with plenty of water. Splashes in the eyes must be treated in the same way (eye wash bottles). Inhalation of alkylamine vapors must be avoided. Clothing splashed with the product must be changed immediately. If the eyes are damaged, a doctor must be called at once. Copyright © 2021 US Amines

US Amines HOME ABOUT PICTORIAL IMPRESSIONS PRODUCT INFO TECHNICAL INFO SALES CONTACT CHEMICAL REACTIONS Chemical Reactions Amines are capable of entering into a variety of reactions because of the replaceability of the hydrogen atoms attached to the nitrogen and because of the basic functionality of the nitrogen atom. They are therefore important intermediates for chemical syntheses. Thus, examples of products obtained by reacting amines are as follows: with carboxylic acid chlorides, carboxylic acid anhydrides and also esters: substituted acid amides, with phosgene: isocyanates, carbamoyl chlorides, urea derivatives, with alkylene oxide: alkoxylated amines, with short-chain alkyl halides and dialkyl sulfates: quaternary ammonium compounds, with carbon dioxide: N-alkylcarbamic acids, on heating under pressure with carbon dioxide: N,N'- dialkyl ureas, with isocyanates: substituted urea derivatives, with aldehydes or ketones: Schiff bases. Some reactions can be performed selectively only with primary, secondary or tertiary amines: primary and secondary amines with acrylonitrile yield: aminopropionitriles, which can be hydrogenated to diamines and polyamines, primary or secondary amines with monochloroacetic acid or its esters or with unsaturated acids yield: N-alkylamino acids, tertiary amines with hydrogen peroxide form: amine oxides Copyright © 2021 US Amines
