Abstract The effects of particle size on the apparent kinetics carbothermal reduction process phosphate rock were studied by non-isothermal thermogravimetric analyses. Phosphate various was reacted with coke and silica under high purity argon atmosphere. kinetic model parameters reaction different sizes derived combination model-free (Flynn–Wall–Ozawa, Kissinger–Akahira–Sunose, Tang, Starink) m...

This study was conducted to establish effective reduction strategy during the manufacturing process of rice cakes. Simple washing (3 times) and ultrasonic (40 kHz, 10 min) were used in process, sodium hypochlorite (100 ppm, 5 chlorine dioxide (20 as chemical disinfectants. Combination treatment using two disinfectants also performed. The more than cleaning a single each method, showed greater e...

In this paper, two novel alkali clearable disperse dyes were synthesized. 4-flourosulfonyl aniline and 2-nitro-4-flourosulfonyl aniline were utilized as the diazo components and 2- naphthol as the coupling component. The DSC, FTIR, 1HNMR and UV-Vis analyses were used to characterize the synthesized intermediates and dyes. The synthesized dyes were used to dye polyester fibers and their dyeing p...
