To assess the surface characteristics, composition and release of components of Polyvinyl siloxane (PVS) impression material and explore the use of the material other than for impressions. Forty samples of 0.5-mm thickness and 8-mm diameter PVS disks, with ew perforations, were prepared and divided into four groups. Group 1 in methanol was analyzed by GC-MS immediately and on 1st, 7th and 14th day. Group 2 and 3 placed in 10 mL of human saliva and in artificial nasal fluid, resp., were analyzed by GC-MS at 24 h. Group 4 was subjected to surface characteristics anal. by placing five PVS disks each in 1 mL of human saliva and 1 mL of artificial nasal fluid, resp. On Day 1, Dodecanoic acid, Me ester, Cyclononasiloxane, octadecamethyl, Cyclodecasiloxane and eicosamethyl (four peaks) were observed in Group 1. At 24 h, Group 2 had addnl. compounds of 2-Decene,7-methyl-(Z)-, 2-Undecene,8-methyl-(Z)- and Lauryl acetate. Group 3 showed release of 32 compounds, but their retention time was less. Surface characteristics on Day 14 revealed no noticeable changes. The study revealed that there was a lack of any adverse component release from PVS for a period of 2 wk based on GC-MS anal. This study involved multiple reactions and reactants, such as 3,7-Dimethyloctan-1-ol (cas: 106-21-8Formula: C10H22O).
3,7-Dimethyloctan-1-ol (cas: 106-21-8) belongs to alcohols. Alkyl halides are often synthesized from alcohols, in effect substituting a halogen atom for the hydroxyl group. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Formula: C10H22O
