The invention relates to a process to produce HCFC-244bb from HCFO-1233xf wherein, in one embodiment, co-feed species HFC-245cb is added to the reaction at a pressure of at least about 100 psig; and in another embodiment it is added to maintain a mole ratio of HFC-245cb to HCFO-1233xf of between about 0. Group 13 metal alkoxides having flame retardant properties may be prepared by reacting the group 13 metal trihydroxide with an alcohol. Substantially simultaneous with the outputting of the phantom samples from the queue, at least some data samples of at least one encoded unit are decoded and queued behind the phantom samples.
