Any chem people??

I know theres alot of smart people here so....


I have some solvent which is probably 10-16y/o(at the oldest as the
copyright date on the container seems to be 1985) from long time ago
and I am not sure whether it is good or not. This is no longer
available so I don't want to just discard it yet. The solvent in concern
is about 2 liters of cleaning grade 1,1,1-trichloroethane and I heard
this solvent usually contains stabilizer to prevent breakdown and
forming of hydrochloric acid. I have an electronic grade 1,1,1 in a
spray can(very little left though.. about 50cc at most) too and I
compared its acidity side by side. I used a reagent from chemistry kit
called bromocresol green .02N. The reagent is blue and turns green in
alkali and turns yellow in acid. When it was mixed with the electronic
grade TCE it did not change, however it did turn yellow when it was
mixed with cleaning grade TCE. I am sure this is a bad sign, but how
bad is it? I was able to fix it by mixing a small sample of TCE w/
solid lye in a little container, but is this feasible? I am not really
sure, because I have no idea whether or not caustic soda can destroy
TCE. What about solubility? I really don't want lye or resulting
product, sodium chloride dissolved in TCE. We all know salt and caustic
in metal cleaner is big woes. I got it from a hardware store few month
ago and apparently this has been on their shelf for long time.

Even though its been over a month, If I tell them it was illegal(few
years ago EPA banned selling of TCE containing product in consumer
products)for them to sell it to consumers at the time of my purchase do
you think they'll give me a refund on this?

Also would it be illegal to dispose it by letting it evaporate in a
pan outside?

Throw it on a little child to see what happens.

CLICK MY LINK. I HAVE A FORUM!! COME TO MY FORUM, PLEASE???

In retrospect, I probably should have taken the vanilla icecream. But the chocolate looked far too tempting. Little did I know at the time, it was actually little children all mushed up into a fine icey paste. Needless to say, I didn't sleep well that night, and neither did those kiddies. Well, I didn't stand for such a crime!! NO WAY. I marched back in that store and demamded an explanation. And there is was. Double chocolate icecream. Sitting there, waiting to be ingested. Oh, the taste. Oh the pure orgasmic feeling when you consume the delicious cream. Oh, how I love chocolate icecream.

if your children are blue and three apples high, you'll know why.
