Quality Control of 3,5-Dimethyl-1H-pyrazole. I found the field of Polymer Science very interesting. Saw the article Synthesis of blocked waterborne polyurethane with 3,5-dimethylpyrazole for industrial application in digital inkjet printing published in 2019.0, Reprint Addresses Wang, XM (corresponding author), Sun Yat Sen Univ, Minist Educ, Sch Chem, Key Lab Polymer Composite & Funct Mat, Guangzhou 510275, Guangdong, Peoples R China.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.
In this article, a series of blocked waterborne polyurethanes (BWPUs) were synthesized by isophorone diisocyanate, polyols, dimethylol butanoic acid (DMBA), and 3,5-dimethylpyrazole. BWPUs were applied to digital inkjet printing of textiles. The successful synthesis and deblocking of BWPU were confirmed by Fourier transform infrared spectroscopy and differential scanning calorimetry. The colorfastness was improved by deblocking the terminal NCO groups at 140 degrees C, which could react with fiber. This article presented a characterization method of filtering rate to evaluate the fluency of inkjet printing. Besides, the digital microscope was used to investigate the pigment transferred to the white test cloth. In the end, we chose poly(ethylene glycol adipate) 2000 as the polyol, 1,4-butanediol as the chain extender, 1.6 as the NCO/OH molar ratio, and 4% as the mass fraction of DMBA.
