标题:碳氢化合物在氢氟烃中的溶解度估算
摘要:已经开发出用于氢氟碳化合物(hfc)的新溶解度参数sp(sp = 1.175 Ln(np)+ 0.025 H-0.063 F-0.028α-0.018β,其中np取决于摩尔体积和摩尔折射率;h和f分别是分子中氢和氟的数目;而α和β分别是hcf和hccf连接的数目.sp的价值hfc已被用来预测hfc在25oc下对于各种碳氢化合物是否是非常好的溶剂.在异构hfc族中,对烃具有最大溶解能力的单个hfc是那些氟与氢的分离度最大的hfc.将希尔德布兰德溶解度参数δ与半经验sp值进行比较.

摘要:Novel fluorinated carboxylic acid derivatives of the general formula: ##STR1## wherein Rf is a divalent perfluoroalkyl or perfluoropolyether group and Z is halogen, hydroxyl or triorganosiloxy are useful intermediate for the synthesis of various fluorinated compounds. Compounds [I-i] wherein Z in formula [I] is F are prepared by reacting acid fluoride-terminated compounds of the formula: ##STR2## with an alkali fluoride and further with an allyl halide. Compounds [I-ii] wherein Z in formula [I] is a halogen are preparred by reacting compounds [I-i] with lithium halide. Compounds [I-iii] wherein Z in formula [I] is OH are prepared through hydrolysis of compounds [I-ii]. Compounds [I-iv] wherein Z in formula [I] is triorganosiloxy are prepared by reacting compounds [I-iii] with a triorganosilylating agent.

摘要:[Problem] The present invention provides a novel synthesis technique by applying esterification that does not use protonic acid to a silicon-containing compound such as an organopolysiloxane. The purpose of the present invention is to provide a method for producing, through a novel esterification method, an organopolysiloxane that contains a (meth)acryloyl group. [Solution] A method for producing a (meth)acryloyl group-containing organopolysiloxane, the method being characterized by including a step for obtaining the (meth)acryloyl group-containing organopolysiloxane by causing a reaction between (A) a hydroxyl group-containing organopolysiloxane represented by average formula (1) [Chemical Formula 1] (In the formula, the R1s each independently represent a substituted or unsubstituted alkoxy group or monovalent hydrocarbon group having 1 -10 carbon atoms, or a monovalent hydrocarbon group or (poly)oxyalkylene alkyl group having a hydroxyl group at the end (hereinafter collectively referred to as the hydroxyl group-containing group), at least one among the R1s is a hydroxyl-group containing group, a is a positive number of 2 or more, b is 0 or a positive number, c is 0 or a positive number, d is 0 or a positive number, and 2 ≤ a+b+c+d ≤ 1,000.) and (B) (meth)acrylic acid in an amount where the molar ratio relative to the hydroxyl group of the (A) component is 1.0 or greater, said reaction being caused in the presence of (C) an iron compound in an amount where the molar ratio relative to the hydroxyl group of the (A) component is 0.005-0.1.
