Acetic Acid (C2H4O2)

Guide by: humanoferth

Acetic acid can be made as early on as LV and is used in a variety of lines and recipes. Notably, it's used in the production of Polyvynil Butyral and later on the production of Polyimide.

Making Acetic Acid

Distillation

This recipe takes Fermented Biomass and outputs a variety of organic materials, including a small amount of Acetic Acid.

Fermented Biomass to Acetic

It can also be obtained from an MV distillery on circuit 1 with the same input.

This should not be the method used to obtain any amount of Acetic Acid en mass since other methods are both faster and easier, though its still worth setting up for the other materials.

This recipe takes Wood vinegar and outputs a variety of organic materials, including a small amount of Acetic Acid.

Wood Vinegar to Acetic

It can also be obtained from an MV distillery on circuit 1 with the same input.

This method is better then using Fermented Biomass, as its easier to obtain Wood Vinegar from other distillations and from the Pyrolose oven.

Chemical Reactors

These recipes can use either regular or large chemical reactors. While they are faster than distillations, they do require that you have the reagents on hand or passived somewhere else.

This recipe takes Carbon, Hydrogen, and Oxygen on circuit 4.

Acet from Elem

This recipe is a good choice once you have the LCR and can take advantage of the perfect overclock. It's also only one step, which is a nice bonus.

This recipe takes Ethylene and Oxygen on circuit 2.

Acet from Ethy

While this is a good recipe, Ethylene has much better uses then for Acetic Acid. Keep in mind that while the recipe is LV, Ethylene requires MV to make.

This recipe takes Hydrogen and Carbon monoxide on circuit 2.

Acet from Mon

This recipe is faster then making it from its elements, though it does have a higher energy cost. It's also one of the few recipes fully available in LV, though it's not worth making at that point since you don't have access to the Formic Acid Loop.

This recipe takes Methanol and Carbon Monoxide and methanol on any circuit.

Acet from Meth

This recipe is not as good as the Hydrogen + Carbon monoxide recipe, as Methanol requires MV to make and by that point Hydrogen + Carbon Monoxide is viable.

There are a couple more recipes for making Acetic Acid with chemical reactors, though they are not as useful as the ones previously described and should be avoided if at all possible:

  • Reacting Acetic Anhydride and Aminophenol.
  • Reacting Methyl Acetate, Water, and Sodium Hydroxide (Sodium Hydroxide is not consumed, requires MV).
