The next major discovery in this field, which was the result of a joint research effort in 1968 between M and T Chemicals, Inc., and the Dow Chemical Company in the United States (475, 524), was that tricyclo-hexyltin hydroxide ("Plictran ) possesses a very high activity against certain types of mites, and this compound was subsequently introduced by Dow as an acaricide for use on apple, pear, and citrus-fruit trees. A second triorganotin acaricide, bis(trineophyltin) oxide ("Vendex or "Torque ), has recently been introduced by Shell Chemical Company (476). Two other tricyclohexyltin compounds are currently under de-...

Sulfinol A process for removing hydrogen sulfide, carbon dioxide, carbonyl sulfide, and organic sulfur compounds from natural gas by scrubbing with di-isopropanolamine dissolved in a mixture of sulfolane and water. Developed in the 1960s by Shell International Research Mij N.V, The Netherlands and Shell Development Company, Houston. In 1996, over 180 commercial units were operating or under construction.

Meanwhile, Arnold Beckman (b.1900), hitherto a manufacturer of electronic pH meters, had joined forces with Robert Brattain - the brother of Walter Brattain of transistor fame - at Shell Research, with the encouragement of the U. S. Government s Rubber Reserve Company. Beckman s first commercial infrared spectrometer, the IR-1, was developed in 1942 and was used by the wartime synthetic rubber research program. However, the classified nature of this and similar work meant that Beckman spectrometers were not generally available until 1945, when the IR-2 was marketed. Meanwhile, in Britain, Adam Hilger and Grubb Parsons independ-...

David Morgan is a member of the Chemical Ecology Group at Keele University. He was bom in Newfoundland and had his university education there, at Dalhousie University and University of King s College in Halifax, Nova Scotia, and at Oxford. His doctorate thesis was on the lipids of Mycobacterium tuberculosis. He later worked at the National Institute for Medical Research in London, and for Shell Chemical Company and Shell Research under the direction of Sir Robert Robinson, O.M., Nobel Laureate. From 1966 he has been at Keele in Staffordshire as lecturer, senior lecturer, reader, and professor. He discovered the natural pesticide azadirachtin and collaborated with S. V. Ley for its final structure elucidation. He is the author of over 300 papers and reviews, mostly on insect chemistry, editor, and contributor to several volumes and author of the book Biosynthesis in Insects. ... 

AE and AES samples were commercial or developmental ENORDET surfactants from Shell Chemical Company except for AES 810-2.6 supplied by GAF Corporation. AESo and AEGS surfactants were experimental research samples synthesized in our laboratories or were supplied by Koninlijke/Shell Laboratorium Amsterdam with the exception of AESo 911-2.5, 911-3.25, 911-4, and 1215-12 obtained from Diamond Shamrock Corporation. 

Alcohol ethoxylates and alcohol ethoxylate derivatives were chosen for study based on their predicted foaming properties, thermal and chemical stability, salinity tolerance, and adsorption characteristics. Table 1 illustrates the classes of surfactants used and the shorthand surfactant naming system employed. Except when noted, surfactants were developmental ENORDET surfactants from Shell Chemical Company or were research samples synthesized in our laboratory or at Koninlijke/Shell Laboratorium, Amsterdam. AES 810-2.6A was obtained from GAF Corporation.
