I don't know what a URL is . I used the yahoo.com search engine with words cement composition . Then scrolled down to see a listing showing cement is 57% calcium oxide (lime) . Yes I did make...

I looked in a Condensed Chemical Dictionary giving , Portland Cement - A type of hydraulic cement in the form of finely divided grey powder composed of lime , alumina , silica and iron oxide as...

Cement is partly calcium oxide . One molecule of water adds to one molecule of calcium oxide to make calcium hydroxide . CaO + H2O ------> Ca(OH)2 . So some water is removed from the reaction in...

I did the proceedure on 9/17/2017 , my notes on it aren't very good . First I used Magnesol on new corn oil to remove as much of the free fatty acids as I could , so that wouldn't complicate my...

Part of the idea of using cement is for calcium oxide in the cement to react with water produced by the methanol potassium hydroxide reaction to produce methoxide and water . The calcium oxide...

I'll mention , Portland Cement is about 60% calcium oxide , made from limestone . Methoxide made with calcium oxide has some of the calcium hydroxide dissolved in the mix . So calcium soap is...

I took organic chemistry in college for two semesters . If I recall correctly the professor said , generally for a ten degree celcius temperature increase the reaction rate is twice as fast . There...

In United States politics today is proposed "The Green New Deal' , by liberals . There is talk of zero carbon emissions and stopping fossil fuel . It will not happen . It's pre-election propaganda ,...

There are at least 2 ways to make methylated seed oil . One is transesterification of vegetable oil with methanol using caustic as a catalyst . Another way is to make free fatty acids from vegetable...

JimV8; I make small amounts of biodiesel . I dry washed some of it with magnesium silicate . Maybe that's another issue . After treating the product biodiesel with magnesium silicate it's allowed...

In the United States I believe commercial diesel fuel contained 5% biodiesel . A problem with biodiesel and even diesel can be low temperature . Biodiesel is usually a mixture of fatty acid methyl...

I can answer a part of the question . When I burned kerosene it produces soot , usually . But when I burned kerosene in an old hand held blow torch , no soot was produced . I don't know why , but...

For cool weather use of biodiesel there is fractional crystallization . The temperature is lowered some as solids formed they are separated from the liquid . In this way a lower temperature...

Without doing much research , I've read in the USA gasoline was down to one USA dollar per gallon . The Russians and Saudi Arabians had a recent price war on petroleum , selling for five USA dollars...

INFOPOP is down , so is Biodiesel Forum Ireland . One of the latest unanswered question on Biodiesel Forum Ireland was doing pyrolysis of plastics and or used vegetable oil to obtain useful...

I am still here . I made biodiesel from acorns 3/5/2011 . I used a solvent extraction method to obtain the vegetable oil . I don't have the numbers in front of me but I might have got 5% oil from...

3DB I heated a round bottom boiling flask in a pan of hot vegetable oil. During the experiment the oil overflowed on the hot heating element. Vegetable oil expands in volume as it gets hotter. ...

I didn't express what I meant to write simply. It's likely that with elevated temperature the plastic in a tote would be more vulnerable to chemical attack. I made methyl salicylate once, putting...

I made biodiesel from new corn oil , potassium hydroxide , calcium oxide and methanol in a 1 liter glass bottle at room temperature. It's not all that slow. A problem was keeping the methoxide...

Under reacted biodiesel would have mono and di glycerides in it. Not titrating may cause soap excessive due to possible high titrating oil. I would experiment with 1/2-1 litre product in washing to...

I was interrupted while typing a reply. To continue, I made potassium or sodium soap from sodium or potassium hydroxide, on purpose. So I made normal soap. I put maybe 1/4 gram of the known...

Acetic acid is a stronger acid than free fatty acids. The sodium or potassium salt of free fatty acids (soaps) switch the sodium or potassium to acetic acid giving sodium acetate salt and the free...

With my purified biodiesel distilled water poured right through it to form two layers (phases) quickly. So there maybe another issue. If soap content is an issue sodium chloride, table salt, might...

Vegetable oil expands when it is heated. I had a hot vegetable oil bath overflow due to expansion of the hot oil. I don't know how to calculate that mathmatically. It might be measured...

Dr Mark Are you still drying your methoxide solution prior to the transesterification reaction? Maybe drying with cement? Le Chatlier's principle would indicate one advantage to that in the...
