1,2-Propanediol (cas: 57-55-6) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.SDS of cas: 57-55-6

Functional papermaking additives have tremendous potential for application in multipurpose paper. In this research, a functional paper internal sizing agent based on waterborne polyurethane-grafted collagen hydrolyzate (WPUC) was first prepared via free-radical emulsion polymerization of vinyl monomer-modified collagen hydrolyzate and waterborne polyurethane (WPU). Then, the prepared WPUC was used as an internal sizing agent for sustainable processing and manufacturing of the handsheets. FTIR, XRD, DSC, and other anal. techniques were used to characterize the behavior and effects of WPUC internal sizing on the handsheets. The research found that the tensile coefficient, the tear coefficient, the folding resistance, and Cobb60 of the handsheets reached 55.8 N.m.g-1, 1.9 mN.m2.g-1, 12 times, and 190 g/m2, resp., when the WPUC sizing agent was 2% in the pulp. In addition, when the precipitated calcium carbonate (PCC) and WPUC were incorporated in the pulp, the retention rate of PCC could be greatly increased without affecting the mech. properties of the finished paper. Specifically, when the PCC dosages were 25 and 50% in the papermaking, the PCC retention rate of handsheets with the WPUC sizing agent increased correspondingly by 139.2 and 174.5%, resp. Moreover, the handsheets had good water resistance. The results indicate that the WPUC is expected to be used as a novel paper internal sizing agent to further improve the paper performance as well as lower the production costs. In the experiment, the researchers used many compounds, for example, 1,2-Propanediol (cas: 57-55-6SDS of cas: 57-55-6).
