چکیده
In order to achieve a clean synthesis process of HMX,nitrolysis of DPT in two nitration systems was investigated.Nitrolysis of DPT in N2O5/organic solvent systems was investigatedto yield little HMX but mainly complex by-products with lowmelting point, indicating that the solutions of N2O5 in organicsolvents was not suitable for this process. Nitrolysis in N2O5/HNO3system was investigated. The effect of reaction time, reactiontemperature, amount of ammonium nitrate and ratio of raw materialson the yield of HMX were studied, finding that yield of HMXincreases first and then decreases along with the increasing usage ofN2O5 and N2O5/HNO3 system was suitable for the nitrolysis ofDPT because it could give HMX in a high yield up to 58% and purityof 99% under optimized conditions: n(N2O5):n(DPT)=2:1,n(HNO3):n(DPT)=36:1, react time 30 minute and react temperature25 .

Concentration of Colourful Wild Berry Fruit Juices by Membrane Osmotic Distillation via Cascade Model Systems
Fresh juices of colourful wild berries: cornelian cherry, blackthorn, white beam and elderberry are considered as valuable, highly nutritive beverages and characterized by the high level of vitamins and antioxidant capacity. The concentration process of these juices by membrane osmotic distillation was studied, where only water vapour is eliminated, while the heat sensitive, valuable compounds ...
متن کاملA Novel Bio-based Sulfonic Zwitterionic Surfactant Derived from Transgenic Soybean Oil and its Performance in Surface and Interfacial Activities
Bio-based surfactants have attracted increasing attention due to their renewable resources and excellent surface properties. In this study, a novel bio-based sulfonic zwitterionic surfactant (BSZS) derived from transgenic soybean oil was prepared using a simple reaction route with two steps of the amidation and quaterisation. The bio-based sulfonic zwitterionic surfactant showed a critical mice...
متن کاملEffects of Valproic Acid on Axonal Regeneration and Recovery of Motor Function after Peripheral Nerve Injury in the Rat
Background: Valproic acid (VPA) is used to be an effective anti-epileptic drug and mood stabilizer. It has recently been demonstrated that VPA could promote neurite outgrowth, activate the extracellular signal regulated kinase pathway, and increases bcl-2 and growth cone-associated protein 43 levels in spinal cord. In the present research we demonstrate the effect of VPA on peripheral nerve r...
متن کاملChemoradiotherapy alone or in combination with Endostar for patients with advanced non-small cell lung cancer: A systematic review and meta-analysis
Previous studies show inconsistent effect estimates for the efficacy of Endostar in patients with advanced non-small cell lung cancer (NSCLC) undergoing chemoradiotherapy. Therefore, this meta-analysis aimed to determine the effectiveness and safety on the basis of data obtained from available randomized controlled trials (RTCs). We find relevant articles reporting the use of Endostar combined ...

متن کاملDevelopment of a rapid, one-step-visual method to detect Salmonella based on IC-LAMP method
Background: Salmonella can cause serious human gastroenteritis and is frequently isolated from various food samples. The cell culturing, immunoassay, and polymerase chain reactions (PCR) are the current methods to detect such pathogenic agents. However, these methods are time-consuming and labor-intensive, and thus unavailable for rapid-monitoring of Salmonella</em...
