DESIGN AND SYNTHESIS OF NOVEL ANTIMICROBIAL ACYCLIC AND HETEROCYCLIC DYES AND THEIR PRECURSORS FOR DYEING AND/OR TEXTILE FINISHING BASED ON 2-N-ACYLAMINO-4,5,6,7-TETRAHYDRO-BENZO[B]THIOPHENE SYSTEMS

A series of novel polyfunctionalized acyclic and heterocyclic dye precursors and their respective azo (hydrazone) counterpart dyes and dye precursors based on conjugate enaminones and/or enaminonitrile moieties were synthesized.The dyes and their precursors are based on 2-cyano-N-(3-cyano-4,5,6,7-tetrahydrobenzo[b]thiophen-2-yl)-acetamide, 2-ethoxy

As the modern aviation-oriented business model (aerotropolis), the Airport Economy Zone (AEZ) accumulates capital, technology, workforce, and other production factors.The AEZ always has a large number of infrastructure investments.Still, it has not yet achieved the expected effect in integrating 5-HTP and driving other regional resource endowments

In order to establish the effect regulation of surface topography characteristic parameters on gear dynamics performance,measurement of fractal dimension for gear surface and its efficiency and vibration are tested in the condition of different lubrication.Based on three sets of gearbox with the same tooth 5-HTP surface accuracy level,the tooth con
