Description

Location: RER - Europe
This dataset represents the production of dimethenamide (1 kg of active ingredient). Raw materials are modelled with a stoichiometric calculation. Energy consumption is modelled with data from a similar process. The emissions are estimated. Infrastructure is included with a default value.
[The full documentation of this dataset was originally provided in the corresponding ecoinvent report from the Swiss Centre for Life Cycle Inventories, which is accessible for free to guests and users of ecoinvent version 2 (https://www.ecoinvent.org/login-databases.html). The dataset may subsequently have been subjected to central changes to the database, as described in the respective change report for each new release.]
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.

Technology

Dimethenamide is a pesticide produced in nine steps from ethylene:
C2H4 + CO + H2O → C3H6O2
C3H6O2 + Cl2 → C3H5ClO + HCl
C3H5ClO + NaSH + H2O → C3H5O2SNa + HCl + H2
C3H5O2SNa + HCl → C3H6O2S + NaCl
C3H6O2S + C4H6O2 → C7H12O4S
C7H12O4S → C6H10OS + CO2 + H2O
C6H10OS + C4H11NO → C10H19NOS + H2O
2 C10H19NOS + 2 SOCl2 → 2 C10H17NOS + SO2 + S + 4 HCl
C10H17NOS + C2H2Cl2O → C12H18ClNO2S + HCl
Precursors that are used for the dimethenamide production are chloroacetyl chloride (C2H2Cl2O), methacrylic acid (C4H6O2), 1-methoxy-2-amino-propane (C4H11NO), sodium hydrogren sulfide (NaSH), and thionyl chloride (SOCl2).
Chloroacetyl chloride (C2H2Cl2O) is produced in two steps from acetic acid:
C2H4O2 + Cl2 → C2H3ClO2 + HCl
C2H3ClO2 + SOCl2 → C2H2Cl2O + HCl + SO2
Methacrylic acid (C4H6O2) is produced in three steps from acetone:
C3H6O + HCN → C4H7NO
C4H7NO + H2SO4 → C4H9NO5S
C4H9NO5S + H2O → C4H6O2 + NH4HSO4
1-Methoxy-2-amino-propane (C4H11NO) is produced in two steps from propylene oxide:
C3H6O + NH3 → C3H9NO
C3H9NO + CH4O → C4H11NO + H2O
Sodium hydrogen sulfide (NaSH) is produced from hydrogen sulfide and sodium hydroxide:
H2S + NaOH → NaSH + H2O
Thionyl chloride (SOCl2) is produced in two steps from sulphur:
S + Cl2 → SCl2
SCl2 + SO2 + Cl2 → 2 SOCl2
