Cm F2m+1-b H b -O-Cp F2p+1-c H c (B)
[ 式中、m とp は互いに独立して 1〜4 であるが、(m+p) は5 を超えず、そして(b+c) は1 〜(m+p+1) である]
で表されるフッ素化エーテルである。
C m F 2m+1-b H b - O- C p F 2p+1-c H c (B)
[ 式中、mとpは互いに独立して1〜4であるが、(m+p)は5を超えず、そして(b+c)は1〜(m+p+1)である]
で表されるフッ素化エーテルを含む、CFC−113の代替用流体に関する。
高い水素含有率を有する化合物は概して可燃性であるため、一般に水素原子の数は多くともフッ素原子の数と同数である。それ故、本発明の態様の一つでは、上記フッ素化エーテルは、難燃性であり、かつ水素原子の数が多くともフッ素原子の数に等しい。
しかし、本発明は純粋物質に限られず、それどころか、入手しやすく、その為安価であるという簡単な理由による好都合を度々有する適当な液体の混合物をも包含する。しかし、本発明は、沸点を低くするために混ぜ合わされた適当な液体の混合物にも関する。
本発明には、非限定的に、以下の態様が含まれ得る。
・少なくとも 3個の炭素原子を有するアルカン及び/ またはジアルキルエーテルの一連から得られる、実質的にフッ素化された難燃性化合物を伝熱剤として使用する方法。
・伝熱剤が、(a)前記式(A)のフッ素化されたアルカンまたは前記式(B)または(2)のフッ素化されたエ−テルあるいはそれらの混合物と、これらと混合された(b)可燃性低級炭化水素、可燃性低級アルカノ−ルまたは可燃性低級ジアルキルエ−テルからなり、但し(a)と(b)からなる伝熱剤は難燃性である、同方法。
・伝熱剤が共沸混合物である、同方法。
・前記化合物を、同様の沸点または沸騰範囲を有するクロルフルオルカーボンの代用物として使用する、同方法。
・少なくとも 3個の炭素原子を有するアルカン及び/ またはジアルキルエーテルの一連から得られる、実質的にフッ素化された難燃性化合物と、低級炭化水素、ジアルキルエーテル及びアルカノールの一連から得られる可燃性液体との混合物が難燃性となるように上記難燃性化合物を上記可燃性液体と混合して、それを伝熱剤として使用する、同方法。
・少なくとも 3個の炭素原子を有する炭化水素またはジアルキルエーテルの一連から得られる、実質的にフッ素化された難燃性化合物と低級アルカノールとの共沸混合物を伝熱剤として使用する、同方法。
本発明のフッ素化エーテルは、CFC−113(1,1,2- トリクロル-1,2,2- トリフルオルエタン) の代替品として有用であり、それ故、本発明の更に別の対象は、本発明による上記フッ素化エーテルを含む、CFC−113の代替用流体である。
