THE CHEMIST'S RECIPIE FOR CHOCOLATE CHIP COOKIES

The following recipie for chocolate chip cookies recently appeared in Chemical & Engineering News (C&EN, Jun 19, 1995, p. 100). It was attributed to Jeannene Ackerman of Witco Corp.

Ingredients:
 1. 532.35 cm3 gluten
 2. 4.9 cm3 NaHCO3
 3. 4.9 cm3 refined halite
 4. 236.6 cm3 partially hydrogenated
    tallow triglyceride
 5. 177.45 cm3 crystalline C12H22O11
 6. 177.45 cm3 unrefined C12H22O11
 7. 4.9 cm3 methyl ether of
    protocatechuic aldehyde
 8. Two calcium carbonate-encapsulated
    avain albumen-coated protien
 9. 473.2 cm3 theobroma cacao
10. 236.6 cm3 de-encapsulated legume
    meats (sieve size #10)
To a 2-L jacketed round reactor vessel (reactor #1) with an overall heat-transfer coefficient of about 100 Btu/F-ft2-hr add one, two, and three with constant agitation.

In a second 2-L reactor vessel with a radial flow impeller operating at 100 rpm add four, five, six, and seven until the mixture is homogeneous.

To reactor #2 add eight followed by three equal portions of the homogeneous mixture in reactor #1. Additionally, add nine and ten slowly with constant agitation. Care must be taken at this point in the reaction to control any temperature rise that may be the result of an exothermic reaction.

Using a screw extrude attached to a #4 nodulizer place the mixture piece-meal on a 316SS sheet (300 x 600 mm). Heat in a 460K oven for a period of time that is in agreement with Frank & Johnston's first order rate expression (see JACOS, 21, 55), or until golden brown.

Once the reaction is complete, place the sheet on a 25 deg. C heat-transfer table allowing the product to come to equilibrium.

Silver Nitrate
(to the tune of "Silver Bells")

Silver nitrate, silver nitrate
it's chemistry time in the lab
Ding-a-ling, with a copper ring
soon it will be chemistry day.

Take your nitrate, in solution
Add your copper with style
In the beaker there's a feeling of reactions
silver forming, blue solution
Bringing ooh's ah's and wows
now the data procesing begins.

Get the mass, change to moles
what is the ratio with copper?
Write an equation, balance it
we're glad it's Chemistry Day.

Cesium (Burning in the Dead of Night)
(Tune, Blackbird)

Cesium burning in the dead of night.
Take your sky blue lines and start to shine.
All my life,
I was only waiting for the moment you were mine.

Cesium burning on a lake of ice.
Lift your glorious flame up to the skies.
All your life,
You were only waiting for some water to arise.

Cesium burn.
Cesium burn.
Give your light to this coal black night.

--- Songs of Cesium #133

Test Tubes Bubbling
(to the tune of "Chestnuts Roasting On An Open Fire")

Test tubes bubbling in a water bath
Strong smells nipping at ypur nose.
Tiny molecules with their atoms all aglow
Will find it hard to be inert tonight.

They know that Chlorine's on its way
He's loaded lots of little electrons on his sleigh
And every student's slide rule is on the sly
To see if the teacher really can multiply.

And so I offer you this simple phrase
To chemistry students in this room
Although it's been said many times, many ways
Merry molecules to you.
