Dimethyl carbonate (DMC) 1050 g Assumption: Created in SimaPro using Ecoinvent data for reagents of carbon monoxide, oxygen, and methanol according to Tundo and Selva (2006). This amount of DMC is used in different parts of the procedure.
3-methyl-4-nitroimino-perhydro-1,3,5-oxadiazine 184 g Assumption: Used generic Diazine Compound present within Ecoinvent database as substitute.
2-chloro-5-chloromethylthiazole 168 g Assumption: Created in Ecoinvent database using information present in Decker
Tetramethylammonium hydroxide pentahydrate 4 g Assumption: Created in Ecoinvent database using information present in Walker
Potassium carbonate 242 g  
Water 900 g Deionized water
Hydrochloric acid 260 g  
Energya
Heat to 65°C 157.54 kJ Assumptions: Mass: sum of all compounds for the first mixture. Initially at room temperature.
Heat at 62°C to 68°C 18.73 kJ Assumptions: The sum of all compounds mass in the mixture are used in the calculation. Initial temperature=62°C.
Cool to 47°C 65.55 kJ Assumptions: When 99% of product is formed, the mixture is cooled. Total mass of reagents used as mass.
Heat to 65°C 111.04 kJ Assumptions: The mass used was the sum of a possible product of 200 g+the water and hydrochloric acid. Initial temperature is 45°C.
Heat to 65°C 125.7 kJ Assumptions: The mass used was the final mass after the heating. The initial temperature was room temperature after waiting for phase separation.
Cool at 65°C to 5°C 188.55 kJ Assumptions: The mass used was the final mass after the heating.
Cool at 5°C 1 kWh Electricity used to keep the mixture temperature at 5°C for 1 hour, 1 kW power requirement
Vacuum at 70°C 176.77 kJ Assumptions: the mass used was the sum of a possible product of 200 g+the water and 300 grams of DMC. Initial temperature is room temp.
a: In all calculations of required energy at each heating/cooling phase, the specific heat of water was assumed, along with a heat exchanger efficiency of 80%.
