摘要:
1,1,1,3,3,3-Hexafluoroisopropanol (HFIP) substantially free of 1,1,1-trifluoroacetone (TFA) can be separated from a mixture containing both compounds by A) catalytic reduction with hydrogen followed by fractional distillation; B) cooling to a temperature at which HFIP freezes and TFA remains liquid; C) forming a high boiling complex comprising HF and TFA followed by fractional distillation; or D) producing HF-free conditions to yield a HFIP/TFA azeotrope followed by fractional distillation. It is emphasized that this abstract is provided to comply with the rules requiring an abstract, which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR § 1.72(b).

摘要:
A clipboard with fold-out, extendable legs. This allows the user to set the extended legs on the floor leaving the clipboard standing in a horizontal position at a convenient hip height. With this, the user has both hands free for the task and a practical, convenient place for the clipboard to rest. With the legs in the extended position, it is strong enough to write on and light enough to pick up and move to a new location
摘要:
There is disclosed a coating matrix of an extremely thin or monolayer coating for glass or other beverage packaging surfaces. More specifically, there is disclosed materials that can be used to improve the shelf life of packaged materials, such as bottled beer. More specifically, there is disclosed an anti-oxidation coating comprising a cross-linked monolayer that has a hydrophobic character and bound to beverage packaging surface through surface hydroxyl groups and a silane moiety. Moreover, there is disclosed a metal ion chelating moiety as part of the coating matrix.
