Chemical Engineer Chocolate Chip cookie recipe

Chemical Engineer Chocolate Chip Cookies

The following recipe for chocolate chip cookies appeared in Chemical & Engineering News (June 19, 1995). It was attributed to Jeannene Aackerman.

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

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 460 K 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 C heat-

transfer table allowing the product to come to equilibrium.

What'er My God Ordains Is Right
text: Samuel Rodigast (1675)
music: David Braud

1. Whate’er my God ordains is right,
Holy His will abideth
I will be still whate’er He does,
And follow where He guideth
He is my God, Though dark my road
He holds me that I shall not fall
Wherefore to Him I leave it all

2. Whate’er my God ordains is right,
He never will deceive me
He leads me by the proper path,
I know He will not leave me
I take, content, what He hath sent
His hand can turn my griefs away
And patiently I wait His day

3. Whate’er my God ordains is right,
Though now this cup in drinking
May bitter seem to my faint heart,
I take it all unshrinking
My God is true, each morn anew
Sweet comfort yet shall fill my heart
And pain and sorrow shall depart

4. Whate’er my God ordains is right,
Here shall my stand be taken
Though sorrow, need, or death be mine,
Yet I am not forsaken
My Father’s care is round me there
He holds me that I shall not fall
And so to Him I leave it all

My Fall Thing dress and a gang at Grace Community church

Hello everyone!!! This week marks the date for Fall Thing! For those of you who don't know, it is a semi-formal event where you go and have a great time socializing! (All while being dressed up!) I'm going with a group of kids from Grace Community Church which will be fun since I dont know them that well. One of the girl's dad works at the Master's Seminary and I think we will be going over to her house before hand to eat something and take pictures, so that will be fun to meet her parents.


So, I thought I would post pictures of my dress, (especially for my mom who wants to see it!)
