It is shown that the introduction of nitrogen-containing monomer units, N-(dibutylaminomethyl)methacrylamide, into composition polymers higher alkyl acrylates increases their efficiency in process low-temperature solution dewaxing oil raffinates various compositions.

The oil content of the wax produced in a dewaxing process is the key economic parameter that should be reduced as much as possible. Some factors such as the type of solvents, cooling rate, temperature, and solvent to oil ratio influence the dewaxing process. Due to the fact that crude oil differs from place to place and since the operational conditions for wax extraction vary for different type...

Developing highly selective and efficient bifunctional catalysts is an important issue for the hydroisomerization of long-chain n-alkanes. It vital to tailor balance isomerization cracking reactions in hydroisomerization. Herein, a Pt/hierarchical SSZ-32 catalyst was fabricated with sequential desilication–dealumination treatment boost n-hexadecane (C16). The pore structure acid sites zeolite w...

Reduced acid-fast staining of leprosy bacilli occurs during the dewaxing of paraffin sections by xylene and alcohols; the older and more decrepit bacilli being especially affected. By the use of non-deparaffinized sections, the leprosy bacilli which could not be stained with the usual carbol fuchsin are strongly stained. Moreover, non-deparafinized sections can be used for the periodic acid-car...

The transfer of mid-infrared spectral histopathology to the clinic will be possible provided that its application in clinical practice is simple. Rapid analysis formalin-fixed paraffin-embedded (FFPE) tissue section thus a prerequisite. chemical dewaxing these samples before image acquisition used by majority studies contradiction with this principle. Fortunately, silico images acquired on FFPE...
