Where is butylamine found?
It is one of the four isomeric amines of butane. It is known to have the fishy, ammonia-like odor common to amines. Found in mulberry leaves, kale, swede, tomato, wheat bread, cheeses, caviar, raw fatty fish, cooked chicken or beef, beer, cocoa, and other foodstuffs.

What is butylamine used for?
Butylamines are organic amines of butane, used primarily as intermediates in the manufacture of a variety of chemical products. Some butylamines are used as food additives. Butylamines are flammable, colorless liquids with a fishy, ammonia-like odor.
Is butylamine a base?
Butylamine is a base (Kb = 3.98×10-4). Hydrochloric acid is a strong acid, so it will convert the butylamine into the butylammonium ion by a neutralization reaction.
How do you make N-butylamine?
It is produced by the reaction of ammonia and alcohols over alumina: CH3(CH2)3OH + NH3 → CH3(CH2)3NH2 + H2O. n-Butylamine is a weak base.
What is permissible exposure level?
Definition. A Permissible Exposure Limit (PEL) is the maximum amount or concentration of a chemical that a worker may be exposed to under OSHA regulations. A Time-Weighted Average (TWA) is explained below. A VPEL or Vacated PEL is an older PEL set by OSHA but later “vacated” (retracted) under court order.
What is Threshold Limit Value TLV of hydrogen sulphide?
ACGIH® recommends a threshold limit value (TLV®) of 1 ppm as an 8-hour time weighted average (TWA) and a short-term exposure limit (STEL) of 5 ppm.
What is the OSHA standard for benzene?
OSHA. Abstract: Amendment of existing standard for Occupational Exposure to Benzene. The revised standard reduces the permissible exposure limit (PEL) from 10 parts benzene per million parts of air (10 ppm) to an eight (8)-hour time-weighted average (TWA) of 1 ppm and a short-term exposure limit (STEL) of 5 ppm.
How toxic is butylamine inhalation?
No other data on acute inhalation toxicity are available on which to base the IDLH. Other animal data: Rats have survived a 4-hour exposure to 2,000 ppm [Cheever et al. 1982]. It has been stated that butylamine is more than twice as toxic as ethylamine by the respiratory route [ACGIH 1991].
What are the literature references for 1-bromopropane?
Literature References ACGIH: Documentation of the Threshold Limit Values (TLVs) and Biological Exposure Indices (BEIs) – 1-Bromopropane. See annual publication for most recent information. International Chemical Safety Cards (WHO/IPCS/ILO): 1-Bromopropane.
What is 1-butylamine?
1-Butylamine is found in alcoholic beverages. 1-Butylamine is found in mulberry leaves, kale, swede, tomato, wheat bread, cheeses, caviar, raw fatty fish, cooked chicken or beef, beer, cocoa, and other foodstuffs. 1-Butylamine is a flavouring agent. Butylamine is an organic compound, specifically, an amine.
What is the revised IDLH for n-butylamine?
Basis for revised IDLH: The revised IDLH for n-butylamine is 300 ppm based on acute inhalation toxicity data in animals [AIHA 1960; Smyth 1956] and an analogy [ACGIH 1991] to ethylamine which has a revised IDLH of 600 ppm. 1. ACGIH [1991]. n-Butylamine.
