Sodium Hypochlorite combined with ethanol and propanol
« on: March 30, 2013, 02:56:30 PM »
Hello everyone,
I am looking for the what you get when equal parts bleach (5.25%) and rubbing alcohol are mixed?  And also when bleach and ethanol are mixed? 
A chemical formula reaction would be great if possible.
Thanks

Review the last line here:  http://en.wikipedia.org/wiki/Sodium_hypochlorite#Reactions  The exact reaction is your responsibility.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

Thank you for the response.
But I am still unsure of what I will be left with once the two are mixed.
I am neither a chemist or a student.
I know someone who uses this combination to clean and am very interested in EXACTLY  what is being produced, if anything, when they are mixed.
I figured I would try this forum to find out, in addition to other sites on the internet, but it's surprisingly difficult to find the answer to this question. 
I really don't know where to go from here.  Maybe call the local high school and ask the chemistry teacher?!
Thanks again.

I considered it was a possibility that you weren't a college chemist student, but then, why did you ask for the exact chemical reaction?  At any rate, you can still use the Wikipedia page, for this question, and any others.  The last reaction says the sodium hydrochlorite coverts an alcohol to a carbonyl compound.  And the word carbonyl is a hyperlink, so you can find out what that is -- the corresponding carbonyl to ethanol is acetaldehyde. http://en.wikipedia.org/wiki/Acetaldehyde  But I don't know how rapidly that happens in water solution.

I know it has been awhile since the OP has posted, but I wanted to point out that simply mixing bleach in most common solvent alcohols will not result in any reaction.  A fancy catalyst is required for a reaction between bleach and alcohols such as methanol, ethanol or propanols.  Alcoholic bleach is well known for improved biocidal behavior, notably, less sitting time is needed to have the same biocidal effectiveness as bleach alone.

A study on the relative effectiveness of buffered methanolic bleach solutions is: Death, J. and Coates, D. Journal of Clinical Pathology, 1979, 32, 148-153.
