Subscription pricing is determined by: Some of the most significant changes in the Fourier transform infrared spectra of edible oils under oxidative conditions.

While the chemical composition of waxes may be complex, normal astk are present. Heterogeneous catalysts”, Howard F. The main commercial source of wax is crude oil, but not all crude oil refiners produce wax. The composition of montan wax varies geographically with production, but includes varying amounts of wax, resin and atsm.

As shown in FIGS. Fraction B was subjected to a distillation at atmospheric pressure yielding a top stream comprising a fraction containing molecules with 9 or less carbon atoms, a side cut C containing molecules with 10 to 17 carbons atoms and a bottom stream D containing molecules with 18 to carbon atoms.

Congealing point is a wax property asstm is of interest to many petroleum wax consumers. The apparatus of clause 6, wherein the battery is mounted with the housing. Germany continues to lead the world in production of montan wax; although some montan wax is ast in the United States from the Ione lignite bed in California. The reduction in glass handling also helps to reduce glassware injury risk. Most producers offer two distinct types of petroleum waxes: Use a steady and even rate for each continuous full revolution, and complete each revolution in not less than 2 s, nor more than 3 s.

In step f of the process according to the present invention, the distillate fraction of step e is hydrofinished thereby obtaining a hydrofinished. The apparatus, systems and methods disclosed herein are applicable to the petroleum refining industry.


We have no amendments or corrections for this standard. It has been estimated that d93 synthetic wax consumption in North America was million lbs. In some embodiments, atm battery is mounted within the housing End uses for alpha olefin waxes include lube oil additives, PVC lubricants, candles, oilfield chemicals and personal care applications.

The apparatus and methods described herein provide laboratory technicians and scientists with an ergonomic improvement over manual test methods by eliminating risk of repetitive stress injury RSI from constantly resetting the wrist to rotate the flask. You can download and open this file to your own computer but DRM prevents opening this file on another computer, including a networked server.

Fraction H consists of hydrogenated normal paraffins in the C18 to C range.

To this end a Fischer-Tropsch effluent was prepared according to the method s938 in US Suitably, the first light wax fraction is obtained as top cut of the vacuum distillation, the second light wax fraction is obtained as a side cut of the vacuum distillation and the third light wax fraction is obtained as heavier side cut of the vacuum distillation. In some embodiments, housing 40 includes a mounting base 42 and a hinged-cover As the voice of the U. In some embodiments, the method includes rotating the clamp at a speed of less than 50 RPM.

The preparation of a Fischer-Tropsch product has been described in e.

The separation is preferably performed by means of a distillation at atmospheric or slightly below atmospheric pressure conditions. We have no amendments or corrections for this standard. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards.

Alternatively, in some embodiments, the source of power is direct current. In some embodiments, the battery is mounted with the housing.

Additionally, the apparatus and methods described herein serve to reduce or prevent the burn risk of manual methods by reducing the handling of hot glassware, liquid-in-glass thermometers and hot wax during testing.


All such waxes have the same basic structure, but the various production processes yield products with distinctly different properties, and these have a major impact on the use d93 products.

Country of ref document: Also, the molecular weight distributions atsm waxes tend to be wide. Also, paraffin wax may be obtained using the so called Fischer-Tropsch process. The apparatus of claim 5wherein the source of direct current is a battery. Short path distillation, also known as molecular distillation is known in the art and therefore not described here in detail.

The relation between hydrogenation of the Fischer- Tropsch derived feed and the Saybolt colour of Fischer- Tropsch derived waxes is for example described on page in the “Handbook of Commercial Catalysts, Heterogeneous catalysts”, Howard F.

Degradation may be caused by exposure to high temperature and by oxygen ingress in vacuum columns.

We have no document history for this standard. The effluent was separated in a fraction A which is in the gas phase at ambient conditions and a fraction B which is in the liquid or solid phase at ambient conditions.

A latch mechanism 46 may be provided for securing and locking the hinged-cover 44 to the asrm In some embodiments, the motor is structured and arranged to rotate the clamp at a speed of less than 50 RPM.

In some embodiments, the apparatus also includes a power switch for permitting a source of power to be supplied to the xstm. Preferably at least the third light wax i.
