摘要:A single-step, one-pot process to obtain zotarolimus and other rapamycin derivatives on large scale is presented, which improves currently available synthesis schemes. In one embodiment, dried rapamycin is dissolved in isopropylacetate (IPAc). The solution is cooled, and 2,6-Lutidine is added, followed slowly adding triflic anhydride at −30° C. Salts are then removed by filtration. Tetrazole, followed by a tert-base diisopropylethylamine (DIEA) is added to the triflate solution. After incubation at room temperature, the product is concentrated and purified by a silica gel column using THF/heptane as eluant. The fractions containing the product are collected, concentrated, and purified again using an acetone/heptane column. The product containing fractions are concentrated. The product is dissolved in t-BME and precipitated with heptane. The solids are dissolved in acetone, treated with butylated-hydroxy toluene (BHT), and the solution concentrated. The process is repeated twice with acetone to remove solvents. At least one stabilizing agent is added, such as BHT at 0.5% before drying.

摘要:The invention relates to a process for the production of synthesis gas by partial oxidation from a hydrocarbon stream containing plastic liquefaction oil, comprising: a) providing a composition stabilized against premature polymerization comprising: 1) a hydrocarbon stream containing at least 2 wt% of plastic liquefaction oil which is containing contaminants, the remaining part of said hydrocarbon stream being a diluent, 2) at least one additive capable to reduce gums formation or buildup, 3) optionally at least one additive which is a dispersant agent, b) an optional purification step to trap silicon and/or metals and/or phosphorous and/or halogenates over at least one trap to obtain a purified composition, c) gasifying by partial oxidation the stabilized composition provided in step (a), or the purified composition provided in step (b), in a partial oxidation gasification unit to produce synthesis gas comprising at least dihydrogen, carbon monoxide, and carbon dioxide.

摘要:The invention provides an improved synthesis method of L-theanine, the process has optimized and easy-to-operate reaction conditions: the L-theanine is prepared by reacting L-pyrrolidone acid and anhydrous ethylamine with antioxidant existence and under the condition of eliminating air by dry ethylamine, and the reaction temperature is between 30-59 , and the reaction pressure is between 0.4-5.9 Mpa. The yield of L-theanine by the present method is obviously higher than that prepared without antioxidant and dry ethylamine to eliminate air.
