    摘要： Effects of Oxygen on grease or another organic paste product can be evaluated with a modified version of the ASTM D942 test methodology for oxidation stability of lubricating greases or other organic paste products by employment of an oxidation pressure vessel, in which at least one of (A) a very small sample of the grease or other organic paste product is deployed for testing within the oxidation pressure vessel such that the sample has an enhanced surface area to mass ratio, and (B) a temperature other than about 99° C. is employed during the testing. In general, the testing is carried out under oxidation pressure conditions. The sample may be evaluated with respect to Oxygen uptake. Additional technique(s) directed to oxidation and/or other properties of the sample may be carried out before to after any Oxygen uptake evaluation, for example, FTIR analysis and/or ATR-FTIR analysis.

    摘要： The novel organoboron reagent of the present invention is useful in the preparation of unsubstituted propargylic alcohols. This compound reacts with aldehydes and ketones cleanly to afford propargylic alcohols in excellent yields. Unsubstituted propargylic alcohols are important synthetic intermediates in the synthesis of a number of natural products. In addition, the novel organoboron reagent of the present invention also demonstrates diastereomeric selectivity when reacted with enatiomerically pure aldehydes.

    摘要： Grease wear test device includes a body in a form of a collar having an outer surface, a first side and an opposing second side, which are open to form a hollow, open channel through the body, which has a center axis, into which opposing vee blocks can be inserted; and perpendicular to the center axis, a pair of opposing holes through and open to the outer surface of the body and the cylindrical inside wall, through which a cylindrical test journal (falex pin) can be inserted for contact in general with opposing vee-shaped channels of the inserted, opposing vee blocks, and for rotation during testing. The device can be used to modify a falex pin and vee block device, to receive and contain a small sample of grease or another organic paste product for testing such as a modified version of an ASTM D2670 test method for measuring wear properties of fluid lubricants (falex pin and vee block method).

    摘要： An active pharmaceutical ingredients (API) or related substance (RS) can be tested for stability by placing the API or RS in an instrument containing a pressure-controllable atmosphere, controlling the pressure of the atmosphere in the instrument for a predetermined time, and evaluating the API or RS for stability. Testing can be carried out also at predetermined temperature(s) and/or under the influence of gaseous trigger(s) and so forth. For instance, an API sample can be placed in a bomb test instrument/reactor, oxygen as a gaseous trigger can be introduced to contact the API sample under constant and/or ramped temperature(s) and elevated pressure(s) for predetermined time(s), and the API sample can be evaluated for stability. An insert carousel may hold a sample of API(s) and/or RS(s) and/or aliquot(s) of sample(s) of API(s) and/or RS(s) for insertion into the bomb test instrument/reactor.
