Editing Chemistry

{{Template:OutOfDate}}

This will be where stuff about chemistry goes. Feel free to edit as you like; I'm starting with lists of reagents and glassware that I will be bringing, and will add photos as time goes on.

All images are from Wikipedia and used under the [http://www.gnu.org/copyleft/fdl.html GFDL].

>==Glassware==

All items are 24/40 standard taper unless otherwise specified. Some items are not glassware, but are used in reaction setups.

Prices are from Sigma-Aldrich's catalogue. In reality these can be had much more cheaply on ebay.

[[Image:Separatory funnel.jpg|right|thumb|A separating funnel, also known as an addition funnel or a dropping funnel. This one contains ether (on top) and water (on bottom), which are immiscible liquids.]]

[[Image:One arm Erlenmeyer.PNG|right|thumb|A one-arm Erlenmeyer flask, also known as a Buchner flask. The &quot;arm&quot; is ridged so that a hose will stay on.]]

==Reagents==

* 1 gallon methanol
* 1 gallon phosphoric acid
* 1 gallon hydrochloric acid, 12M
* ~1lb potassium hydroxide
* Calcium chloride, anhydrous (drying agent)
* Magnesium sulfate, anhydrous (drying agent)

==Things that are broken but could be fixed==

* A 500mL round-bottom longneck distillation flask with the distiller arm broken off. If someone has an acetylene torch, this could be repaired by fusing a glass tube onto it, or the hole could be sealed up and the flask used for a reflux reaction flask.
* A Liebig condenser, not standard taper, with part of the stillhead end in several pieces. Again, fixable with a hot enough torch.
* A vacuum aspirator with a bunch of pipe-fitting adapters. It works, but currently the adapters are on there really tight and I can't get them off. If someone has a plumber's wrench and a bench vise, this is easy to fix.

==Workshops we could do==

* Distillation and drying. 99% ethanol is really expensive, but we can make it cheaply with everclear (or cheap vodka) and a little bit of work.
* Liquid-liquid extraction and organic separation -- polar vs. non-polar solvents, how to use them
* Column chromatography
* Steam extraction from organic materials -- make your own essential oils and hydrosols
* Acid/base extraction
* Build a rotary evaporator
* How to set up a reaction under reflux conditions
* Fractional distillation
* Build a fume hood

==Things we should have on hand==

There are many reagents which we should have in stock and which can be acquired easily from hardware stores or photography supply stores. Here are some, please add more:

* Acetone (hardware store)
* Xylene (hardware store)
* Toluene (hardware store, though do they sell it in California?)
* 99% isopropyl alcohol (pharmacy)
* Glacial acetic acid (photography supply)
* Dichloromethane (hardware store)
* Denatured alcohol (hardware store)
* Naphtha (hardware store)
* 99% ethanol (can be purchased at places like The Science Shop in San Jose, but is very expensive; cheaper to make our own)
* Silica gel (finer ground than the stuff that comes in packets, but we can grind it up in a mortar)
* Calcium chloride (hardware store, "Damp-Rid")
* Magnesium sulfate, anhydrous (pharmacy; buy Epsom salts and bake them in an oven to dehydrate, then put in a bag and crush into little chunks)
* Astroglide, glycerin/paraben-free (for greasing glass joints)
* Nitric acid, 70% (electronics supply -- used for etching PCBs)
