Abstract
Description
圧縮型冷凍機に用いられる冷媒としては、例えば、1,1,1,2-テトラフルオロエタン(R-134a)等のHFC(ハイドロフルオロカーボン)をはじめとした、オゾン層破壊の恐れが少ない各種代替フロンが使われている。
しかしながら、HFCにおいても、地球温暖化能が高い等の問題があり、近年は、地球温暖化係数が低く、地球温暖化に対する影響が少ない冷媒が求められている。このような冷媒として、炭酸ガス(二酸化炭素)、アンモニア、炭化水素ガス等に加えて、ジフルオロメタン(R32)冷媒も検討されている。
仮に、冷凍機の運転中に当該冷凍機用組成物の相分離が生じると、冷凍機の寿命や効率に対して、著しい悪影響を及ぼす。例えば、圧縮機にて、冷凍機用組成物の相分離が生じると、可動部が潤滑不良となり、焼き付き等を引き起こし、冷凍機の寿命の著しい低下につながる。また、蒸発器内にて、冷凍機用組成物の相分離が生じると、分離した粘度の高い冷凍機油の存在が原因となり、熱交換効率の著しい低下をもたらす。
また、特許文献2には、側鎖にオキシアルキレン鎖を有すると共に、炭素/酸素モル比が4.2~7.0としたポリビニルエーテル系化合物を主成分とする冷凍機用潤滑油(冷凍機油)が開示されている。
特許文献1及び2では、上記のポリビニルエーテル系化合物を含む冷凍機油とR32冷媒との相溶性の検討がなされている。
一般的な環境下で使用される冷凍機において、冷媒と冷凍機油とが相分離せずに相溶している温度領域としては、-20~0℃程度が好ましいとされている。
しかしながら、寒冷地でのヒートポンプ用途や低温倉庫での空調用途に使用される冷凍機においては、例えば、-30℃以下でも冷媒と冷凍機油とが相分離せずに相溶していることが求められる。
特許文献1及び2に開示のポリビニルエーテル系化合物を含む冷凍機油においては、R32冷媒との低温側での二相分離温度は-20℃以上であり、上記のような用途で使用される冷凍機に使用するには、更なる改良が求められる。

なお、本発明の冷凍機油及び冷凍機用組成物は、上述の各種冷凍機システムだけでなく、給湯システムや暖房システムに使用されていてもよい。
なお、実施例及び比較例で調整した冷凍機油の性状の測定法は以下のとおりである。
JIS K2283:1983に準拠して測定した。
(2)粘度指数
JIS K2283:1983に準拠して測定した。
(3)数平均分子量(Mn)
ゲル浸透クロマトグラフ装置(アジレント社製、「1260型HPLC」)を用いて、下記の条件下で測定した標準ポリスチレン換算の値を用いた。
(測定条件)
・カラム:「Shodex LF404」を2本順次連結したもの
・カラム温度:35℃
・展開溶媒:クロロホルム
・流速:0.3mL/min
(4)R32冷媒との低温側での二層分離温度の測定
冷凍機油/ジフルオロメタン(R32)=15/85(質量比)からなる混合物(冷凍機油濃度:15質量%)を調整し、当該混合物を耐圧ガラスアンプルに加え、これを真空配管及びR32冷媒配管に接続した。当該アンプルを室温で真空脱気後、液体窒素で冷却して、所定量のR32冷媒をR32冷媒配管を介して、当該アンプル内に採取した後、アンプルを封止した。
次いで、アンプルにレーザーを照射しアンプルの光線透過率を測定しながら、恒温槽中を室温から徐々に冷却し、アンプルの光線透過率が、測定前のアンプルの光線透過率の50%となった温度を、測定対象である冷凍機油のR32冷媒との低温側での二層分離温度とした。
SUS316L製の2L容積オートクレーブ内に、ニッケル珪藻土触媒(日揮触媒化成社製、商品名「N113」)を6g、及びイソオクタンを300gそれぞれ加えた。
オートクレーブ内を窒素置換し、次いで水素置換した後、水素圧を3.0MPaGとして140℃まで昇温し、140℃で30分間保持後、室温まで冷却した。
そして、オートクレーブ内を窒素置換した後、オートクレーブ内に、アセトアルデヒドジエチルアセタールを10gを加え、再び窒素置換し、次いで水素置換した後、水素圧を3.0MPaGとして140℃まで昇温し、140℃で30分間保持した。なお、この際、昇温によりオートクレーブ内の圧力が上昇する一方、アセトアルデヒドジエチルアセタールが反応することにより、水素圧の減少が認められた。水素圧が3.0MPaG以下となった場合は、オートクレーブ内に水素を注入して、水素圧が3.0MPaGを維持するように調整した。
保持後、室温まで冷却して一度脱圧し、再びオートクレーブ内を窒素置換した後、脱圧した。
撹拌機を取付けたガラス製の1Lフラスコに、トルエン133g、エチレングリコールモノメチルエーテル33.6g、及び三フッ化ホウ素ジエチルエーテル錯体(重合触媒)0.2gをそれぞれ添加した。また、別に用意した三角フラスコには、メトキシエチルビニルエーテル500g(4.90mol)を添加した。
そして、撹拌機を作動し、上記1Lフラスコの撹拌された系内に、上記三角フラスコ内のメトキシエチルビニルエーテルを、ポンプによって、5mL/minで54g供給したところで一旦ポンプを停止した。
上記1Lフラスコの系内の温度が上昇したことを確認した後、ポンプを再起動し、当該1Lフラスコの撹拌された系内に、残りのメトキシエチルビニルエーテルを4時間かけて供給し、供給終了後には更に5分間撹拌を続けた。なお、メトキシエチルビニルエーテルの供給中、系内は常に撹拌し続け、系内の温度はウォーターバスを用いて25℃に制御した。
次いで、当該1Lフラスコの系内に、吸着剤を10g添加し、1時間撹拌した。そして、得られた反応液を濾過して濾液を得、ロータリーエバポレーターを用いて、当該濾液から溶媒と軽質分を除去し、粗製品を得た。
その後、調製例1で調製した触媒が有る2Lオートクレーブ内に、得られた粗製品120gとイソオクタン300gを加え、オートクレーブ内を水素置換した後、水素圧を3.5MPaに保ち、系内を撹拌しながら、30分かけて140℃まで昇温し、さらに140℃で3時間反応させた。
反応終了後、反応液を室温まで冷却し、常圧まで減圧した。そして、反応液を濾過し、ロータリーエバポレターを用いて、得られたろ液から溶媒や水分等を除去し、ポリビニルエーテル(1)からなる冷凍機油を得た。
ポリビニルエーテル(1)は、前記一般式(1)中のR1~R3が水素原子である構成単位(a1)を含む。また、仕込み量から推定される、ポリビニルエーテル(1)の全構成単位(100モル%)に対する、構成単位(a1)の含有量は100モル%であり、構成単位(a2)の含有量は0モル%である。

そして、撹拌機を作動し、上記300mLフラスコの撹拌された系内に、上記三角フラスコ内のモノマー混合液を、ポンプによって4時間かけて供給し、供給終了後には更に5分間撹拌を続けた。なお、モノマー混合液の供給中、系内は常に撹拌し続け、系内の温度はウォーターバスを用いて25℃に制御した。
次いで、当該300mLのフラスコの系内に、吸着剤を5g添加し、1時間撹拌した。そして、得られた反応液を濾過し、ロータリーエバポレーターを用いて、当該濾液から溶媒と軽質分を除去し、粗製品を得た。
その後、調製例1で調製した触媒が有る2Lオートクレーブ内に、得られた粗製品120gとイソオクタン300gを加え、オートクレーブ内を水素置換した後、水素圧を3.5MPaに保ち、系内を撹拌しながら、30分かけて140℃まで昇温し、さらに140℃で3時間反応させた。
反応終了後、反応液を室温まで冷却し、常圧まで減圧した。そして、反応液を濾過し、ロータリーエバポレターを用いて、得られたろ液から溶媒や水分等を除去し、ポリビニルエーテル(2)からなる冷凍機油を得た。
