Abstract
Description
[1]下記一般式(1)で表されるα,β-不飽和アルデヒド(以下、アルデヒド(1)と称する)を有効成分として含有する、硫化鉄除去用の組成物。
[2]R1~R3がそれぞれ独立して水素原子または炭素数1~5のアルキル基である、[1]の組成物。
[3]R3が水素原子である、[1]または[2]の組成物。
[4][1]~[3]のいずれかの組成物を硫化鉄に接触させることを特徴とする、硫化鉄の除去方法。
[5]前記組成物中のアルデヒド(1)を、硫化鉄1質量部に対し0.1~100質量部となるように添加する、[4]の方法。
[6]前記組成物中のアルデヒド(1)と硫化鉄を-30℃~150℃の範囲で接触させることを特徴とする、[4]または[5]の方法。
[7]硫化鉄を除去するための、[1]~[3]のいずれかの組成物の使用。
特に、アクロレインを含有する従来の硫化鉄除去剤に比べ、本発明の組成物は毒性が極めて低く、熱安定性およびpH安定性が高いという利点を有する。この理由は必ずしも明らかではないが、アルデヒド(1)はβ位に少なくとも1つのアルキル基、アルケニル基またはアリール基を有するため、β位に置換基を有しないアクロレインと比較し、生体分子や生長鎖などの嵩高い分子のβ位への付加反応が起こりにくいことが要因のひとつと考えられる。一方で、硫化鉄の除去に関しては、硫化鉄と平衡状態にある硫化水素と結合し、これを除去することで硫化鉄の溶解が促進され、結果的に硫化鉄が除去されると考えられるが、β位に置換基を有していても、一般的に小さい分子である硫化水素からの攻撃はさほど阻害されず、硫化鉄除去性能が保たれるものと考えられる。
アルデヒド(1)においてR1~R3がそれぞれ独立して表す炭素数1~10のアルキル基は直鎖状でも分岐状でも環状でもよく、例えばメチル基、エチル基、n-プロピル基、イソプロピル基、n-ブチル基、イソブチル基、t-ブチル基、n-ペンチル基、n-ヘキシル基、n-オクチル基、n-デシル基、n-ドデシル基、シクロペンチル基などが挙げられる。硫化鉄の除去性能の観点から、中でもメチル基、エチル基またはn-プロピル基が好ましく、メチル基またはエチル基がより好ましく、メチル基がさらに好ましい。
R1~R3がそれぞれ独立して表す炭素数2~10のアルケニル基は直鎖状でも分岐状でも環状でもよく、例えばビニル基、アリル基、1-ペンテン-1-イル基、4-メチル-3-ペンテン-1-イル基、4-ペンテン-1-イル基、1-ヘキセン-1-イル基、1-オクテン-1-イル基、1-デセン-1-イル基などが挙げられる。中でも炭素数1~8のアルケニル基が好ましく、炭素数1~6のアルケニル基がより好ましい。
R1~R3がそれぞれ独立して表す炭素数6~12のアリール基は、例えばフェニル基、トリル基、エチルフェニル基、キシリル基、トリメチルフェニル基、ナフチル基、ビフェニリル基などが挙げられる。中でも炭素数6~10のアリール基が好ましい。
また、R1がR2またはR3と互いに連結して炭素数2~6のアルキレン基を表す場合、当該アルキレン基としては例えばエチレン基、n-プロピレン基、n-ブチレン基、n-ペンチレン基、n-へキシレン基、2-メチルエチレン基、1,2-ジメチルエチレン基、2-メチル-n-プロピレン基、2,2-ジメチル-n-プロピレン基、3-メチル-n-ペンチレン基などが挙げられる。
R1~R3はそれぞれ独立して水素原子または炭素数1~5のアルキル基であることが好ましい。
硫化鉄の除去性能を有し、かつ熱安定性およびpH安定性を確保する観点から、R1、R2の少なくとも一方がメチル基であることが好ましく、R1、R2が共にメチル基であることがより好ましい。
また硫化水素との反応を促進し、硫化鉄を効率よく除去する観点からは、R3は水素原子であることが好ましい。
なお、trans体およびcis体を有する化合物については、いずれか一方を用いてもよいし、混合物を用いてもよい。混合物を用いる場合、任意の混合比のものを用いることができる。
また、本発明の組成物はシクロヘキサン、トルエン、キシレン、重質芳香族ナフサ、石油蒸留物;メタノール、エタノール、エチレングリコールなどの炭素数1~10のモノアルコールまたはジオール;などの適当な溶媒を含有していてもよい。
本発明の組成物は好適には液状であるが、硫化鉄を除去するために使用する形態に応じて、適宜担体などに担持させ、粉体、流体などの固体状としてもよい。
