摘要:
Paraffin compositions including mainly even carbon number paraffins, and a method for manufacturing the same, is disclosed herein. In one embodiment, the method involves contacting naturally occurring fatty acid/glycerides with hydrogen in a slurry bubble column reactor containing bimetallic catalysts with equivalent particle diameters from about 10 to about 400 micron. The even carbon number compositions are particularly useful as phase change material.

摘要:
A method for synthesizing 3-oxolupenal nanoparticles including isolating 3-oxolupenal from a fraction of Nuxia oppositifolia plant, reducing the 3-oxolupenal to obtain a powder of 3-oxolupenal, dissolving the powder of 3-oxolupenal in methanol to form a first solution, adding the first solution to boiling water to form a second solution, sonicating the second solution, and freeze-drying after sonication to obtain the synthesized 3-oxolupenal nanoparticles. The synthesized 3-oxolupenal nanoparticles exhibited cytotoxic effects and antimicrobial effects.

Described herein are alkylated imino sugars derivatives having a disease-modifying action in the treatment of diseases associated with glucosidase activity that include viral hemorrhagic fevers and other enveloped viruses, and any other diseases involving glucosidase activity.
摘要:
Provided are a purification device and method. The purification device and method make most use of an internal heat source in the distillation column in the process of distilling the raw material, and reduce use of an external heat source. Thereby, the purification device and method can improve energy efficiency of all the processes.

The present disclosure identifies methods and compositions for modifying photoautotrophic organisms as hosts, such that the organisms efficiently produce alkanes, and in particular the use of such organisms for the commercial production of alkanes and related molecules. Other materials, methods, and compositions are also described.
摘要:
The separation of normal paraffins from non-normal hydrocarbons wherein the paraffins have from about 10 to about 35 carbon atoms per molecule, using a molecular sieve adsorbent having an effective channel diameter of about 5 angstroms wherein an improvement in the process comprises passing a non-normal hydrocarbon input stream into the adsorption zone at adsorption conditions to promote the selective adsorption of the straight chain hydrocarbon constituents of the feed material in contact with the adsorbent in preference to the lighter straight chain hydrocarbon constituents of the desorbent material also in contact with adsorbent.
摘要:
Mixtures of C.sub.12 -C.sub.18 n-paraffins with paraffinsulfonic acids having the same number of carbon atoms, water and sulfuric acid, and obtained by sulfoxidation of said paraffins with sulfur dioxide and oxygen in the presence of water and ultraviolet radiation are stripped of their excess sulfur dioxide and decanted to separate most of the paraffins, and obtain a residual mixture.The residual mixture is fed with sulfuric acid until a two-phase system forms or at least until the mixture becomes turbid, and the turbid mixture or that floating on the heavy water-sulfuric acid phase is extracted with supercritical carbon dioxide, which removes with it the paraffins, which can be reused in the sulfoxidation process.
