Difference in solubility
Brought over from old forumKruger(stranger)07/24/04 08:12 AMdiferential miscibility Has anyone used caster oil for recovery of ethanol?This method is used for separating ethanol from waterbefore distillation giving a higher alcohol content.Post Extras: Print Postpuggy(stranger)07/24/04 08:43 AMRe: diferential miscibility new [re: Kruger] A still does it just fine, actually up to ethanol’s theoretical maximum concentration. So I am not sure about the motivation for a chemical rather than physical separation. It sounds like you are leaning towards an A/B extraction such as that used in pharmaceuticals and by the mighty drug lords of Columbia. Where a desired molecule is first made soluable in a basic solution then precipitated out by forming its polar form. I can’t really recal the whole process from a class I had awhile back, but I don’t know about the precipitation of ethanol? Maybe I am just thinking about something totally different! Add a link to the reference that you are talking about and I will read through it.-puggyPost Extras: Print PostAnonymous(Unregistered)07/24/04 08:57 AMRe: diferential miscibility new [re: puggy] I will try and get hold of the article, but what I read was thattheoretically you could separate the alcohol from the water in the wart before distillation and get a higher yield more efficently. I found the article on http://www.nasatech.comPost Extras: Print PostAnonymous(Unregistered)07/24/04 09:05 AMRe: diferential miscibility new [re: puggy] Here is the full link to that article.http://www.nasatech.com/Briefs/July99/LAR14895.htmlPost Extras: Print PostKruger(stranger)07/24/04 09:58 AMRe: diferential miscibility new [re: Anonymous] Also, could other oils such as used french fry oil be used instead of castor oil?I wish I had a hydrometer and distillation device and I could find out myself.ThxPost Extras: Print Postpothead(enthusiast)07/24/04 10:16 AMRe: diferential miscibility new [re: Kruger] It isn’t hard to build a still. Build one, and give it a try.Read http://acedistiller.com to find out how to build one.Post Extras: Print Postpuggy(stranger)07/24/04 10:27 PMRe: diferential miscibility new [re: Kruger] That is an interesting article! I think it would be a great advancment if it bypassed the distillation step, but the process still uses distillation. It just enhances it by creating a mixture of the oil with ethanol. So it is just distillation. Since the cost of production for consumption is just outright low compared to his taxed cousin, I don’t think it would be worth it. In the case mentioned in the article it was being investigated because it was being suggested as fuel, which doesn’t carry the excise so the inprovement would be noticable. I like that you are interested in advancing the art of distillation.-puggyPost Extras: Print PostKruger(stranger)07/25/04 02:13 AMRe: diferential miscibility new [re: pothead] oh yes, I can’t wait to build my own still.This site is an excellent source of info.I can’t thank you guys enough for your input.Post Extras: Print PostKruger(stranger)07/25/04 02:21 AMRe: diferential miscibility new [re: puggy] Thx for your reply, I’m gonna try calculating the cost of energy used in every step. I know it borders on blasphemy to be using a form of vodka for your automobile, but I’m just curious. I’m thinking of using the differential miscibility procedure with a pot still. Wish me luck.Post Extras: Print PostKruger(stranger)07/25/04 02:24 AMRe: diferential miscibility new [re: Kruger] Just a note, my computer at home went belly up.I’m using the computer at work. My replys will be delayed.Thx again guys.Post Extras: Print Postpothead(enthusiast)07/25/04 05:18 AMRe: diferential miscibility new [re: Kruger] I don’t know where you are from, but using grains,corn,and other fermentables might be cheaper than using sugar. Before you go dumping any ethanol into your car, Remember that ethanol ignites at higher temperature than gasoline, so you might want to put an additive in it to make starting the vehicle easier. Also, if you want to make alcohol fuel, you might be better off using a reflux still…they are alot easier to build than they may seem.Post Extras: Print PostAnonymous(Unregistered)07/25/04 06:03 AMRe: diferential miscibility new [re: pothead] I had planned on buying a flex fuel vehicle.I like my Ford Ranger and they make an E85 version of it. Ethanol is corrosive and you are correct about using it in a regular vehicle without at least making modifications.The cost of sugar, tell me about it, its $1.55 for a 4lb bag.I want to use corn and Indiana is full of it, in more ways than one.Post Extras: Print PostKruger(stranger)07/25/04 06:08 AMRe: diferential miscibility new [re: pothead] The idea I had was to see if I could make an alcohol fuel cheaper than could be had at the gas pumps and then make my fuel as cheap as possible. I think ethanol distillation is the way to go when compared to biodiesel or other fuel alternatives.Post Extras: Print Postpothead(enthusiast)07/25/04 08:24 AMRe: diferential miscibility new [re: Kruger] horse feed grains are inexpensive….ALOT cheaper than sugar, however, you would need amylase enzymes to convert the starches to sugars.check this site out…http://running_on_alcohol.tripod.com/AND…. a good design here…http://journeytoforever.com/biofuel_lib … eCh9a.htmlEdited by pothead (07/25/04 08:28 AM)Post Extras: Print PostAnonymous(Unregistered)07/25/04 09:05 AMRe: diferential miscibility new [re: pothead] Could I use some malted barley or wheat for the enzymes that I need or would just purchasing them be better way?Post Extras: Print Postpothead(enthusiast)07/25/04 09:17 AMRe: diferential miscibility new [re: Anonymous] that would work just fine.Post Extras: Print PostKruger(stranger)07/25/04 10:49 AMRe: diferential miscibility new [re: pothead] Thx for the link to running on alcohol.tripod.Very insightful, I’m gonna check my truck’smanual right now. When I was looking for ethanol containers I saw an article by Fishers about getting ready for the rise in demand for steel tanks due to increasing ethanol production.Light travels faster than sound. That is why some people appear bright until you hear them speak.
