'•F COURSE. REDUCING THE COST OF REDUCING AGENTS IS ETHYLQGICRL
"You know, C2H5, 'Ethyl'aluminum alkyls are so cost-efficient that they're often the reagent of choice, both for organic synthesis and polymer catalysis." "THAT IS fl PREDICTABLE RESULT. THEIR REDUCTION VALUES PER POUND ARE FREQUENTLY SIGNIFICANTLY GREATER THAN THOSE DF OTHER REDUCING AGENTS."
"But even greater cost efficiency can be attained by using the correct reagent for each specific reduction." "YES. FOR EXAfïlPLE, PEOPLE WHO NEED SELECTIVE ACTION ON A CERTAIN GROUP OR POSITION IN AN ORGANIC KTIOLECULE ΠΊΑΥ REQUIRE 'ETHYL' DIBAH [DIISOBUTYLALUmiNUm HYDRIDE]:1
"Just as OMH-1 (sodium aluminum diethyl dihydride) would be a likely choice for other specific synthesis problems. And not only for drug and pesticide manufacture, but for fine chemicals and fragrances J "THIS IS A COIT1PLEX SUBJECT, WORTHY DF INVESTIGATION BY RED PEOPLE IN BOTH INDUSTRIAL LABORATORY AND COLLEGE CHEIÏ11STRY DEPARTmENTS."
"You're quite right... naturally. Real economy in reductions comes as a result of total cost-effectiveness, not initial price." "THEREFORE, OUR EXTENSIVE LITERATURE ON ORGANIC SYNTHESIS AND OUR VARIOUS REAGENTS CAN BE OF GREAT ASSISTANCE."
"Well, we are the world's most experienced producer. So people whofillin the coupon will get plenty of useful information on how to save money in reductions—and how to handle these chemicals safely." "EVEN OUR LITERATURE HAS GREAT COSTEFFECTIVENESS. IT IS ETHYLOGICAL." Please send the following: D 'Organic Synthesis" brochure and supplement. D "Handling Procedures" brochure. Literature on: D OMH-1; D DIBAH; D TIBA D I'd like an "Ethyl" Representative to contact me.
