Location: RER - Europe
The process “triethyl amine, at plant, RER” is modelled for the production of triethyl amine from ethanol in Europe. Raw materials are modelled with a stoechiometric calculation. Emissions are estimated. Energy consumptions, infrastructure and transports are calculated with standard values.
Triethylamine (C6H15N ; CAS 121-44-8) is a colourless liquid with a strong fishy odour. It is s completely miscible with water below about 18 °C but is only partially miscible with water above this temperature.
Triethylamine can be produced by amination of ethanol.
3 C2H6O + NH3 → C6H15N + 3 H2O
Of the three ethylamines, triethylamine has the widest range of uses and is also the most expensive product owing to the unfavorable distribution of monoethylamine, diethylamine, and triethylamine in production. Much of the triethylamine is used as an organic acid acceptor in synthesis or as a salt former in precipitation and purification operations. Important examples of these uses are in the synthesis of semisynthetic penicillins and cephalosporins, and as solubilizers for herbicides in combination with 2,4-dichlorophenoxyacetic acid or 2,4,5-trichlorophenoxyacetic acid. Triethylammonium is the cationic component of the herbicide Garlon 3A (Dow Elanco). Other important fields of use include polyurethane catalysts (for example, the hardening of core sands in cold-box casting), curing catalyst for phenol – formaldehyde resins, anticorrosion agents, paper, textile and photographic auxiliaries, and anodic electrocoating.

Undefined unit processes (UPRs) are the unlinked, multi-product activity datasets that form the basis for all of the system models available in the ecoinvent database. This is the way the datasets are obtained and entered into the database by the data providers. These activity datasets are useful for investigating the environmental impacts of a specific activity (gate-to-gate), without regard to its upstream or downstream impacts.
