This product is the first step in a two-step sequence as per submissions GLS201 and GLS202. This first step is the hydrosilylation of D4' (tetramethylcyclotetrasiloxane) with allyloxydiethyleneoxy methyl ether. The second step, to be carried out at Gelest as well, is to be found in submission GLS202.

Page 16 NON-CBI SUBMISSIONPage 17 NON-CBI SUBMISSIONAt Gelest the standard operating procedure is for the larger reactors, greater than 100L, to be vented directly to a scrubber system thus

minimizing the amount of material released to the atmosphere. Residual organic materials and wash solvents are off-site incinerated. This material would be run in reactors greater than 100L is size. The smaller reactions are run in flasks up to 22L in size and these are carried out in fume hoods that are also connected to the scrubber system. The residuals and wash solvents are off-site incinerated.
