“…The problems encountered by this group may originate in any of the broad fields of the company's interest, such as cellulose and cellulose products, explosives, synthetic resins, insecticides, ter- penes, or rosin and its derivatives. Examples selected from the work of the group over the past fewyears include the development of new methods for analyzing mixed styrenes (4); for the determination of conjugated dienes in pyrolysis products from the cracking of terpenes (9); determination of total volatiles in smokeless powder (10); determination of carboxymethylcellulose in paper (5); and for the direct determination of oxygen in organic compounds (1). Examples of published papers from this group also include: "Potentiometric Titration of Weak Acids in Ethylenediamine" (8), "An Adiabatic Calorimeter" (11), and "Present Status of Intrinsic Viscosities" (3).…”

149sis. Information on the label is transcribed in one typing operation to printed analytical report slips, with interleaved carbon paper, and to printed punch cards. The report slips are used for recording, reporting, and filing the analytical data obtained. The punch card is used first to indicate the progress of the analysis and subsequently to find the original data in a permanent file by a simple hand-sorting procedure. Four categories of information are punched by hand into the card from code lists. This flexible system is applicable to a large or small volume of a wide variety of samples and provides positive control of the progress of the work.It gives much information which leads to improvement of the analytical organization and is helpful in the compilation of operational reports.

“…Putnam, Moss, and Hall (90) recommended the use of chloromaleic anhydride for the determination of conjugated diolefins. This modification of the Diels-Alder procedure offers the advantage of obtaining an adduct that contains an active chlorine atom; this chlorine can then be determined by an argentimetric procedure, the vinyl chlorine of the excess reagent remaining unreactive.…”

“…One general diene method is that of Putnam, Moss, and Hall (11), which utilizes ß-elimination of chloride ion from the adduct of the diene and chloromaleic anhydride. However, chloromaleic anhydride is, unfortunately, less reactive than maleic anhydride.…”
