After using 10ppm KMnO_4 for the treatment of the alcohol from discard molasses and then distilling the liquid, intermediate runnings were collected and poured into water, and the degree of the white spirit was diluted to 54° at room temperature.
Methods:Distill essential oil of Fresh fennel root cultivated in a year and two years and essential oil of dry fennel root cultivated in a year were investigated by simultaneous distillation and extraction,then analyse with GC/MS.
The peaper proposes a processing flowsheet for the distill citrals out from litsea cubebaoil, which is composed of three dishillating steps, used for producting citrals containing 95% and97% and Showed recovery efficienies of 97 .07% and 96. 94% .
This research has investigated the impact on the content of the aroma compounds and component part of the amount of rice used, distill at the same time - extract law (SDE ) , porous resin (XAD-4 ) post absorption method is it separate scented rice meal difference , volatility of compounds to draw, make riper aroma compounds collection method.
The method of intermediate alloy-vacuum distil lation for preparing high-purity dysprosium metal has been studied The influences of raw material purity and impurity removal by vacuum distillation were discussed. The total content of main non-RE metal impurities in the high-purified dysprosium metal prepared is only 705μg/g,and the content of C,N and O is 32μg/g,2μg/g and 50μg/g,respectively.
The classical titration after distillation is used, with ab-sorption by a definite volume of 0.5 mol/L sulfuric acid standard solution, introduction of steam to distil out ammonia under strong alkaline condition, and back-titration of excess sulfuric acid solution with 0.5 mol/L NaOH standard titration solution, to determine the content of diethanolamine (DEA) in the Benfield solution.
Mixing up urea with absolute ethyl alcohol, with thigh H_2SO_4 as catalyst, for 72 hours' reflux, will produce a great amount of white solid NH_4HSO_4. Filter while it is hot; eliminate solid NH_4HSO_4; distil under the normal pressure and extra alcohol will be distilled;
Results:The optimum extracting procedure for naphtha in Chinese Mosla Herb,Herb of Haichow Elsholtzia can be described as warmed dipped for 4 hours,using the distilled speed of 4mL/min100g to distil and it's the best time when distillation quantity has reached 6 times quantity.
policy of distilling truth from foreign bodies, I ask this question urgently.
An impinger is used for sampling, the socket of which is developed in such a way that it can be used as a distilling flask for the absolutely necessary separation of ammonia from interferring substances.
Organ material or blood was destroyed by heating with hydrochloric acid in a closed distilling apparature.
450° C was achieved in the presence of non-carbonizing but distilling organic matrix.
Proteomic analysis of a distilling strain of Saccharomyces cerevisiae during industrial grain fermentation
Production of Environmentally Friendly Diesel Fuel and Petroleum Aromatic Solvents by Extraction Combined with Azeotropic Distil
The effects of the different concentrations of aqueous extracts were compared to distil water (control.).
camara leaf extracts were recorded and compared with control (i.e., distil water).
The pumice is thought to have been lost above the vent or the moving pyroclastic flow, though there is a possibility, yet untested, that it may be contained in the distil part of the ignimbrites.
The purpose of the review is to distil the current knowledge on the structure, and interaction sites on F-actin, of the major, non-motor actin-binding proteins from smooth muscle, proposed to have a role in regulation.
