Products

Goals

Water

Water via distillation
NOWA? Substance Status
NOWA Salt water Pending
LIBR Sea salt Pending
LIBR Distilled Water Pending

Justification

Pure (ish) water is an essential for life, not just chemistry. Preparing it at scale is important.

Path

Distilling impure water gives a distillate with no dissolved solids or biological pathogens. There are compounds which form azeotropes with water, so the distillate may not be completely pure, but it will be adequate for our purposes.

Sodium Hydroxide

Lye via Lime
NOWA? Substance Status
NOWA Limestone Pending
LIBR Calcium oxide Pending
NOWA Wood ash Pending
LIBR Sodium hydroxide Pending

Justification

Sodium hydroxide is a primary industrial chemical and is arguably the most commonly used alkali in chemistry.

Path

We will actually be making a mixture of sodium hydroxide and its cousin potassium hydroxide, but for our early purposes, we will not need to separate them.

Ammonia

Ammonia from urea hydrolysis
NOWA? Substance Status
NOWA Urine Pending
LIBR Urea Pending
LIBR Distilled water Pending
LIBR Sodium hydroxide Pending
LIBR Ammonia Pending

Justification

For each material we set as a goal, we will include our reasons for producing it. Ammonia is an essential industrial chemical. It is the primary source of non-elemental nitrogen. Thus, producing some must be an early goal.

Path

  • In the current period, ammonia is mostly made by the Haber process. Unfortunately this requires high temperatures, high pressures, and catalysts to work at anything more than a "droplets" scale, definitely not benchtop chemistry.
  • Alternatively, we can hydrolyze urea which is a naturally occurring component of the urine of most large animals, including humans. This we can do on a benchtop

Sulfuric Acid

Justification

Path

Next Goal

FAQ

  1. What is NOWA-CL?
    There's a video on that question.
    NOWA stands for Naturally Occurring Widely Available. The CL stands for Chemical Library. This project is about documenting the technological steps involved in developing a library of chemical compounds that can be made with simple equipment from materials that are naturally occurring and widely available. There's no need to order chemicals from supply houses, or obtain them from over-the-counter products. Once a chemical has been produced in quantity from naturally occurring widely available sources, we add it to our "library". Then we can use that material to produce new materials. The important part is to demonstrate that they can be produced from these sources with minimal equipment: what the chemical industry refers to as "small-scale" or "laboratory" synthesis.
    The documentary part of this project will include two main products: the text on this wiki and the videos on YouTube.
  2. So it's a recipe book where people can learn how to make chemicals?
    Definitely not. See the warning on our front page. Chemistry equipment can be dangerous by itself. Many materials (including the ones we work with here) are dangerous: toxic, flammable, corrosive, etc. These operations should not be repeated or reproduced except by people who are sufficiently qualified to do the work and handle the materials safely.
  3. Isn't there a kind of chicken-and-egg problem? What is your equipment made of?
    That's a good point. We assume that the equipment itself (glassware, supports, heat sources, etc) are available at the beginning. The equipment itself may not be naturally occurring, but it's widely available, accessible, and relatively cheap. The purpose of this project is to demonstrate that the process is the important part, not the chemicals you start with. It's the knowledge, not the resources, that enable the science.
  4. There are already too many wikis out there. Why start a new one? (aka Why not just put this information in Wikipedia?)
    1. Aggregating and disseminating this information was the purpose of this project, and wikis are an excellent way to do both of those things, so that part is straightforward.
    2. Wikipedia is specifically not a textbook, guidebook, or instruction manual. That means it isn't appropriate to build out those entries with much of the data in this wiki. To whatever degree it makes sense for both projects, sharing of data is welcomed and encouraged. NB: A lot of the numeric data in this wiki comes directly from either Wikipedia or its underlying sources.

WARNING

ANY pursuit can be dangerous to the inexperienced, unprepared, or incautious. That is definitely the case with the reactions, extractions, and syntheses this project entails. Do not repeat them unless you are sufficiently informed, prepared, and equipped to handle these materials and safely do the work shown.
