Methanol Definition and 47 Threads

Hello I'm trying to get some good reference material so I can do a literature review on Turboprops and a comparison of PSFC of Hydrogen/Methanol/Jet A1 fuels for turboprops. If anyone knows any good source material for this please let me know as I have struggled to find anything. Regards, Michael

This privately held company developed a technology to extract H from methanol stored onboard marine craft, then the H can be used in a fuel cell for power. I assume the reason for a H fuel cell vs a direct methanol fuel cell (DMFC) in a marine vessel is that direct methanol cannot deliver large...

The solution says that when the effusion rate ratio is multiplied by the equilibrium mole ratio of H2 to CH3OH, the effused mixture will have 33.0 times as much H2 as CH3OH. I don't understand why. I just set the equilibrium mole ratio of H2 to CH3OH as equal to 33.0 times, Why is this...

Calculate the boiling temperature of methanol at 60 atm knowing that Tc = 513K, Pc = 78 atm and the acentricity is 0.555. I would like you to help me start the exercise. I thought about using the Pitzer Correlation to be able to calculate the fugacity coefficient, but I don't have the...

I need to find the properties such as specific heat capacity, thermal conductivity, density and others.

Hi I was wondering if anyone could tell if there is a chemical that reacts the methanol but is also safe to consume in small amounts

I was searching for 24 micron counterparts(in the MIPSGAL catalogue) for Methanol Multibeam sources but found them missing for most of the cases. What could be the posssible reason?

I noticed that my windshield washer fluid has methanol in it to reduce the temperature of which it freezes. I know it freezes at approximately -28°C which gives us a concentration of MeOH at approximately ~30% by weight. However, when I try to calculate the required methanol using the mSolute...

For a vessel containing liquid methanol (95%) and other substances (methanol takes up about 40 wt%), which operates at 4.5 bar and 75C, what would happen if the vessel ruptures? SInce it's at a relatively high pressure, the methanol should still remain as liquid and hence no explosion? What kind...

I've been reading that is possible to produce DME (dimethyl ether) from methanol using a catalyst. In the following website: http://www.topsoe.com/products/dme-99-ecotmI've found a catalyst for the dehydration of methanol to produce DME. I would like to know technical information about the...

Hello, Just as the title asks, what sort of applications would series and parallel connections of Direct Methanol Fuel Cell suit the best? Based from my understanding of Fuel Cells and experimental results, one cell is not enough to power anything, hence they are used in stacks, in addition...

Hi, I've recently made some very budget homemade 'beer', butt I'm wondering is there an easy (doesn't have to be accurate) way to determining ethanol and methanol content. any help appreciated.

Hi, I am trying to recrystallize salt from methanol. I am having trouble. This is exactly what I did: I dissolved a gram of salt into 20 ml of methanol (the bottle I have says methyl hydrate but I read online that it's the same thing as methanol). Then I made a hot water bath. I put a pyrex...

I was searching some info in this forum and I found something here: https://www.physicsforums.com/showthread.php?t=160186 As far I know you've to mix carbon dioxide and hydrogen and the result is methanol. I want to understand more technical information, like the amount of each gas that...

PLEASE! I need to find a pressure-temperature phase diagram por PURE methanol! it's driving me mad...

Homework Statement Soooo...looking at Ka values, methanol is more acidic than water. Ethanol is less acidic. I understand that the reason ethanol is less acidic than water is because the ethanol ion has an inductive effect where more electrons are donated to the oxygen, so it being more...

Methane to Methanol Methane to Methanol 2 Hello everyone. In the link above is a pdf from the Department of Energy detailing how they created methanol our of water using a photochemical reactor. Im not sure if I am asking the correct people (you people) but I was wondering if you...

How do I make 7% glacial acetic acid in 40% (v/v) methanol?

I'm trying to get a variety of colored flames by dissolving salt and methanol (after the fashion of this YouTube video et al.: http://www.youtube.com/watch?v=eRNLqTfIjQo"). I'm doing halfway alright with strontium chloride solution and boric acid solution, but having some trouble: the boric...

Hey there. I've been searching the internet on volume contraction with water and methaol mixture. Although I have found a little bit of infomation I don't know why it happens. I found it quite intriguing that mixing 50ml of water and 50ml of Methanol =/= 100ml of liquid. In fact there is a 4%...

According to the Pepsi website, a can of Diet Pepsi has 111mg of Aspartame per container. http://www.pepsiproductfacts.com/infobyproduct.php?brand_fam_id=1051&brand_id=1000&product=Diet%20Pepsi In the body Aspartame metabolises primarily to Phenylalanine ~50%, secondarily to Aspartic Acid ~40%...

Homework Statement What are the two final products when cis-2-butene reacts with HBr and CH3OH? Homework Equations Reactions of Alkenes.The Attempt at a Solution I'm not sure if the HBr will attack the double bond first or if the OH on methane will take the H off HBr and create a radical...

Homework Statement During a lab where the heat of combustion of paraffin and methanol was found, ice was used to lower the temperature of water to 10 C, then the water was heated to 30C. This inturn gave us the information to find the molar heat of combustion. My question is why was ice...

i just started a hobby i couldn't afford till now. radio control cars. iam have been running a nitro truck for 7 mo. i started mixing my own nitro fuel, 30% nitro, 10% oil, rest methanol. i have been measuring by volume. i was told that doing it this way it will be off, by a cretin...

How to prepare a 100mg/ml solution of glacial acetic acid in methanol? The density of glacial acetic acid is 1.05 g/cm^3.

The enthalpy of formation of methanol (-22.7 KJ/g) is about half that of octane (-47.8 KJ/g). But methanol allows an ICE engine to achieve much greater specific powers than a comparable gasoline engine. My RC heli runs on methanol and will outperform any gas powered heli. But why is this? I...

Hey guys. Can someone show me the mechanism for Aspartame to methanol?

I apologize for the fact that I am a complete layman. It might be time for me to go and learn some thermodynamics. I am working on the design for a production lab at my Community College, and while I'm sure we have engineers to do this for us, I was really curious about sizing a boiler. I...

moe in wichita ks if i buy a "gas dryer" methanol. how can i check to see if it has water in it? and if it has water can it be removed?

I have a project that i am doing that requires that i pump methanol at a temperature of about 140F at a volume of about 1 to 2 gpm and a pressure of around 150 - 200 psi. It must be capable of 'run dry' by which i mean that it may not always have fluid to pump. Can anyone give me a lead on a...

Does anyone have coefficients of thermal expansion in F^-1 instead of in C^-1. I have worked out an equation from thermodynamic first principals that derives the throttling equation I then did the first order non-seperable differential equation: dT/dP = C1*T - C2 to get the following...

Hey guys, I was wondering if anyone could help me out with this problem? If you place 10.0L of methanol (CH4O) in a sealed room that is 3 m long, 1.75 m wide, and 2.5 m high, will all the methanol evaporate? If some liquid remains, how much will there be? The vapor pressure of methanol is...
