Making bionapalm?


The idea is to make ecological and natural napalm (as a personal challenge), or something similar where the prefix "bio-" can be assigned.
At least napalm made from biomass.

This requires the same ingredients as to make normal napalm:
- Gasoline.
- Naphtha-palmitic aluminum soap.

The problem is that, according to the challenge, these two ingredients must be obtained from the transformation of biomass, and not from fossil fuels. This means that ordinary gasoline does not work, biogasoline is required. And the same criteria is applied to soap.

.

Step 1: get biogasoline.

As I read, it is possible to make gasoline from biomass, but I don't know how to do it at home.
Mentally improvising, I thought of a recipe similar to biodiesel, but replacing vegetable oil (long chain fatty acids) with animal oils (?), Which contain short chain fatty acids (4-10 carbons).

The underlying logic is that gasoline is composed of short chain hydrocarbons (4-11 carbons), while diesel has longer chain hydrocarbons (with carbon length close to vegetable fatty acids).

Animal fat, butter, for example, contains significant amounts of butyric acid, caprylic acid and caproic acid (all of these polymerized to form lipids, of course), among other short-chain fatty acids. These fatty acids, when not polymerized, are somewhat volatile and have unpleasant odors reminiscent of vomit, cheese, feet, sweat, dirty people and wet dogs.

So the idea is to dissolve caustic soda in wood alcohol (methanol), and mix this solution with animal oils with the hope of producing "biogasoline" and glycerin.
Getting "distill" animal oils (?), Separating lipids from "non-lipids", is a key step that I don't know how to perform.

.

Step 2: get (bio) palmitic acid and (bio) naphthenic acid.

Palmitic acid is not a difficult ingredient to find (palm oil contains 44%) but it is difficult to separate at the home level, requiring fractional distillation equipment or something similar.

Getting naphthenic acid from biomass is a real problem, since the most aromatic vegetable oils usually concentrate 4% or less. It is more viable to synthesize naphthenic acid. Of course, from a naphthenic compound obtained from biomass. I have no idea what to do here.

.

Step 3: make aluminum soap.

Once the previous two (bio) acids have been obtained, new problems now arrive. Aluminum trimethalate, or aluminum alkoxydes, must be manufactured and reacted with these acids. This, again and at home level, is a problem.

Would it be of any use to make sodium or potassium soap and mix it with aluminum trichloride, with the hope it reacts forming aluminium soap and sodium/potassium chloride? I do not believe that...

.

Step 4: tasty tasty jelly.

The naphtha-palmitic aluminum biosoap is mixed with biogasoline to finish making the bionapalm. 100% ecological, natural, healthy and renewable bionapalm (joke).

Should we really go to the trouble of figuring out how to make bio-war weapons.u see we tend to reserve terms like "organic" and "bio" for things that are going to make us healthier and ethically sourced organic napalm or biologically safe napalm sort of goes against that.
Give it up dude.i doubt your gunna get many serious replies.

Why not? If the idea behind the project would be to do harm, person in question could go to a fuel station, get some gasoline and use that right?

Step 1: you don't have to isolate the oils, you can directly do a trans-esterfication on the fat. The mechanism, I believe, is that glycerol separates as a layer, driving the equilibrium. This is done all the time when making biodiesel. You only have to separate the layers.

You don't have to distill anything.

Step 2: Is the other 56% content of palm oil a problem? If not just use palm oil. And; naphthenic acid is not aromatic ;)

Step 3: Making aluminium alkoxides is a lot easier than making aluminium chloride (anh.), get some seaweed, sublime the iodine out and use that to react aluminium foil with an alcohol.
