[Objective] To evaluate the therapeutic effect of Oleum Curcumae Aromaticae (OCA) on leukemia cell strain HL-60 and K562 by observing its sensitivity in inhibiting HL-60 and K562. [Methods] Subculture of HL-60 and K562 cells was performed on the 96-hole culture plate and OCA 100μL at the final concentration of 400, 200, 100 and 50mg/L respectively was added.
The result shows: when the oleum/raw material is 0.4, sulfonation temperature is 50℃, sulfonation time is 50min, 1# can be sulfonated into DYE-1A, and the NaOH-S-P(DYE-lA as surfactant ) compound flooding can low the interfacial tension between oil and water of Oil recovery plant NO. 2 of Daqing oilfield to 1.68 × 10-5 mN-m-1;
Through the discussion of interference factors in determination of volatile phenol and oil in water, the paper gives the methods to solve the problem in predistillation and lower blank absorbability, analyses the influence solvent choice and the use of H 2SO 4、NaCl and anhydrous Na 2SO 4 as well as extractive liquor treatment in oil determination.
When delay time=3500μ seconds,the total oil con-tent of corn seeds measured by pulsed NMR for room dried,presoaked for 8 hours,and60℃ over dried for 96 hours was about the same,indicating that seed moisture conditionhad no significant interference in oil determination.
The accurate waste oil determination value shall be got by adopting mixed oil hydrocarbon as standard sample which supposed in Water and Waste Analysis Method and using of correction coefficient (Here is 0.9),or by adoptiong the mixed oil hydrocarbon type(Ⅰ) as standard sample which manufactured from the experiment.
Combined with the logging example, mainly introduce that BNLL is applied in analysis and evaluation of producing formations,estimation of the residual oil,determination of operating object, and the good geological effect is obtained, BNLL plays more important role in oilfield development.
Analysis of the volatile oil from the stem of Acanthopanax Senticosus (Rupr.
Biorefinery based on biomass resources is an important approach for the oil refining and petrochemical industry to achieve sustainable development.
A W/O microemulsion was prepared with Span80-PS (petroleum sulfonate) as complex emulsifier, isopropanol as cosurfactant and kerosene as oil phase.
Synthesis and properties of oil-soluble butyl crystal violet lactone
The volatile oil, the fraction of petroleum ether: EtOAc = 20:1 (V/V) on Si gel chromatography, was also quantitatively analyzed by gas chromatography mass spectrometry (GC-MS).
Activity of a new antimicrobial preparation from fish oils from various sources: Effects of different factors
Degradation of Petroleum Oils by a Selected Microbial Association
A series of microbial associations capable of the biodegradation of various petroleum oils, emulsols, and crude oil were obtained by selection during periodic or continuous cultivation.
Under these conditions, oils were degraded by 92% on average.
Biochemical Processing of Fats and Oils As a Means of Obtaining Lipid Products with Improved Biological and Physicochemical Prop
The catalytic system proposed by us in which palladium occurs in the form of palladium powder dissolved in oleum has not been described up to now.
Synthesis of New Sulfonic Acid Acrylamide Derivative from Acrylonitrile, Camphene, and Oleum
Benzene, toluene, and 2-chlorothiophene regioselectively react with N-(2,2-dichloro-2-phenyl- ethylidene)arenesulfonamides in the presence of oleum to give N-[1-aryl(or hetaryl)-2,2-dichloro-2-phenylethyl]arenesulfonamides.
1,2-Dinitroguanidine is a product of nitroguanidine nitration with nitric acid and its mixtures with sulfuric acid and oleum.
The nitration of 5-chloropyrazoles with a mixture of 100% nitric acid and 65% oleum or a mixture of 60% nitric acid and polyphosphoric acid gave substituted 5-chloro-4-nitropyrazoles in 45-91% yield.
Both sectorphotometer and microphotometer analyses were carried out on the Hg spectrum transmitted by papers popularly used as window materials in Chinese homes. The intensity distribution of transmitted radiation, after normal incidence, through samples of nine different kinds of paper have been studied, and the total transmission calculated for various wavelengths.
1. A simple method is presented for determining double bond index of pure unsaturated hydrocarbons, petroleum fractions and other hydrocarbon mixtures based on a correlation of observed refractive index, calculated refrac-tive index, molecular weight and the number of double bonds per molecule. The data neccessary are: (a) mid-boiling point, (b) refractive index at 20℃ for sodium D line, (c) density at 20℃ and (d) weight percent hydrogen of the
依据在20℃钠D线折光率实测值,在20℃钠D线折光率计算值,分子量及每一分子内所含双键数间之相互关系,推衍得一简易方法,用以测定纯不饱和烃及石油分馏油份之双键率(Double Bond Index).所需由实验测得之数据为试料之(甲)在20℃钠D线折光率,(乙)在20℃时之密度,(丙)中间沸点(Mid-boiling point),及(丁)含氢重量百分数.用本法测得双键率值,与用尼蒲金(Lipkin),圣金(Sankin)及马丁(Martin)三氏法测得双键率值适相吻合.因此,用本法所测得之双键率,足资用以鉴定石油分馏油份内所含芳香族烃及烯(?)烃之主要型式.惟需指明者,即在依据本法测得之双键率,用以鉴定石油分馏油份内所含不饱和烃之主要型式时,必须测定由石油分馏油份内提出仅含不饱和烃浓缩物之双键率.
Sodium di-n-butyl naphthalene sulfonate was prepared from n-butyl al-cohol, naphthalene and fuming sulfuric acid. Di-isoamyl naphthalene sul-fonate was prepared similarly. Their wetting properties were tested by the modified Draves method. Dibutyl naphthalene sulfonate was found to be avaluable wetting agent and could be made from cheap raw materials.
