The Kleber-Colombes rigid PVC foam (253,254) is produced by compression mol ding vinyl plastisol to react and gel the compound, followed by steam expansion. The process involves mixing, mol ding, and expansion. The formulation consists of PVC, isocyanate, vinyl monomers such as styrene, anhydrides such as maleic anhydride, polymerization initiators, FC-11, and nucleators. The ingredients are mixed in a Wemer-Pfleiderer or a Baker Perkins...

Wlien solid soda ash is used to supply all the carbonate v alues in the precipitation step (eq. 9), a ca 10% Na2S solution results from the primary filtration step wliich can be concentrated to 40% Na2S in a three-effect evaporator train. Final concentration to 60%Na2S occurs in a high v acuurn single-effect evaporator. Hiis concentrated solution can then be fed to a Baker to produce a 60% sodium sulfide flake wliich is sold as co-product.

A baker counts biscuits in dozens—a convenient number. Money is counted in dollars— one hundred cents is, again, a convenient number. How did chemists choose to count in terms of moles—the number 6.02 X 10 seems an odd choice. Why, for instance, didn t they settle on some simpler number, such as exactly one billion particles There is a reason. Chemists prefer a definition in terms of a quantity that can be measured readily and with high accuracy. Weigh-... 

The final ingredient, salt, is added to slow down the rate of fermentation of the yeast. This gives a baker a certain amount of control over the rising process, ensuring that the bread will have the desired texture and will cook evenly. 

After earning a lackluster Ph.D. from the University of Berlin in 1891, Haber wrote a friend, The thesis is miserable. One and a half years of new substances prepared like a baker s bread rolls.. . . One learns to be modest. In preparation for entering his father s business, he studied chemical technology in an alcohol distillery in Hungary, a Solvay soda factory in Austria, and a salt mine in Poland. His obligatory year in the Prussian army left him with a smart, military manner and a love of rank and discipline. His attempts to become a reserve officer failed, however, for this was a prestigious honor reserved for Christians, and Haber was Jewish.
