【0007】
【発明の実施の形態】
本発明のアニオン性界面活性剤において、スルホコハク酸エステル塩(B)は、上記▲1▼〜▲3▼を満たす(A)のスルホコハク酸エステル塩であれば、特に限定されないが、下記一般式(5)で表される塩の1種以上であることが界面活性能の点から好ましい。
[式中、R1 は炭素数8〜24の脂肪族炭化水素基または炭素数8〜24の脂環式炭化水素基;Aは炭素数2以上の1種以上のアルキレン基;kは平均が1〜20となる0または1以上の整数;Z1 およびはZ2 は、いずれか一方がH、もう一方がSO3Q1基を表し、XはQ2 またはR1−(OA)k−基を表す。Q1 およびQ2 は、Hまたはカチオン性対イオンを表す。〕
【0008】
(B)は、さらに、下記一般式(5a)および/または(5b)で表される、モノエステル化物を80〜100質量%、特に90〜100質量%含有し、一般式(5c)で表されるジエステル化物を0〜20質量%、特に0〜10質量%含有するものが好ましい。また、(5a)/(5b)の質量%の比は、好ましくは10〜90/90〜10、さらに好ましくは30〜70/70〜30である。
[式中、R1 、A、k、Q1 およびQ2 は一般式(5)に同じ。〕
【0009】
前記一般式(5)において、R1−(OA)k−O−基は、脂肪族系アルコールアルキレンオキサイド付加物(A)の残基である。Z1 またはZ2 基を形成するSO3Q1基は、例えば、(A)と無水マレイン酸とを反応させたエステル化物をスルホン化することにより導入されるスルホン酸塩基である。Q1 およびQ2 基としては、用いるスルホン化剤の種類により異なるが、水素およびカチオン性対イオンが挙げられる。カチオン性対イオンとしては、例えば、アルカリ金属(ナトリウム、カリウム、リチウムなど)イオン、アルカリ土類金属(マグネシウム、カルシウム、バリウムなど)イオンなどの金属イオン;アンモニウムイオンなどが挙げられる。
【0010】
本発明において、(A)は、脂肪族系アルコール(a1)(本明細書中、脂肪族系アルコールとは、脂肪族アルコールと脂環式アルコールの両者を含むものとする。)にアルキレンオキサイド(b1)を付加して得られる脂肪族系アルコールアルキレンオキサイド付加物の1種または2種以上の混合物であり、下記一般式(1)で表される。
R1−(OA)k−OH (1)
[式中、R1 は炭素数8〜24の脂肪族炭化水素基または炭素数8〜24の脂環式炭化水素基;Aは炭素数2以上の1種以上のアルキレン基;kは平均が1〜20となる0または1以上の整数]
【0011】
上記一般式(1)において、R1 は、脂肪族系アルコール(a1)の残基であり、炭素数が通常8〜24の脂肪族炭化水素基(アルキル基、アルケニル基、アルカジエニル基など)または脂環式炭化水素基(シクロアルキル基、多環炭化水素基など)を表す。R1 は、直鎖状と分岐状など2種以上の基の混合物であってもよい。炭素数8未満では、十分な起泡力、洗浄力が得られず、炭素数が24を超えると起泡力、洗浄力が劣り、好ましくない。
R1 の具体例としては、アルキル基としては、オクチル、ノニル、デシル、ラウリル、トリデシル、ミリスチル、セチル、ステアリル、ノナデシル、2−エチルヘキシル、2−エチルオクチル基などが挙げられる。アルケニル基としては、オクテニル、デセニル、ドデセニル、トリデセニル、ペンタデセニル、オレイル、ガドレイル基などが挙げられる。アルカジエニル基としては、リノレイル基などが挙げられる。シクロアルキル基としては、エチルシクロヘキシル、プロピルシクロヘキシル、オクチルシクロヘキシル、ノニルシクロヘキシル基などが挙げられる。多環炭化水素基としては、アダマンチル基などが挙げられる。
【0012】
一般式(1)中、Aは炭素数2以上、好ましくは2〜8、さらに好ましくは2〜4、特に好ましくは炭素数2または3のアルキレン基を表し、(OA)の部分は、炭素数2以上のアルキレンオキサイド(b1)の付加により形成される。このようなアルキレンオキサイド(b1)としては、エチレンオキサイド(以下、EOと略記)、プロピレンオキサイド(以下、POと略記)、1,2−または2,3−ブチレンオキサイド、テトラヒドロフラン、スチレンオキサイドなどが挙げられる。好ましくはEOおよび/またはPOである。
一般式(1)中、kは(b1)の付加モル数に相当し、平均が1〜20となる整数であり、好ましくは1〜12である。kが20を超えると、十分な起泡力、洗浄力が得られず好ましくない。
【0013】
前記脂肪族系アルコール(a1)は、R1 残基を与えるものであり、炭素数が通常8〜24(好ましくは12〜18)のアルコールであり、天然アルコールでも合成アルコール(チーグラーアルコール、オキソアルコールなど)でもよい。具体例としては、オクチルアルコール、ノニルアルコール、デシルアルコール、ウンデシルアルコール、ドデシルアルコール、トリデシルアルコール、テトラデシルアルコール、ヘキサデシルアルコール、オクタデシルアルコール、ノナデシルアルコールなどの飽和脂肪族アルコール;オクテニルアルコール、デセニルアルコール、ドデセニルアルコール、トリデセニルアルコール、ペンタデセニルアルコール、オレイルアルコール、ガドレイルアルコール、リノレイルアルコールなどの不飽和脂肪族アルコール;エチルシクロヘキシルアルコール、プロピルシクロヘキシルアルコール、オクチルシクロヘキシルアルコール、ノニルシクロヘキシルアルコール、アダマンチルアルコールなどの環状脂肪族アルコールが挙げられ、これらの1種または2種以上が使用出来る。これら脂肪族系アルコールは1級または2級が好ましく、さらに1級が好ましい。また、アルキル基部分は直鎖状でも分岐状でもよい。特に好ましくはドデシルアルコール、トリデシルアルコール、テトラデシルアルコール、ヘキサデシルアルコール、オクタデシルアルコールである。
【0014】
(A)としては、工程が煩雑でないことから、(a1)と(b1)から直接製造されたものであることが好ましい。ここで、「直接製造された」とは、上記付加物が、精留などにより未反応アルコールや付加モル数の異なるものを分別する操作なしで、直接得られたものであることを意味する。但し、分別を目的としないで、簡単な操作で未反応アルキレンオキサイドや低沸点物をストリッピングしたものは分別操作に含まれない。
【0015】
また、本発明で、(A)は、重量平均分子量(Mw)と数平均分子量(Mn)との比:Mw/Mnが下記関係式(2)または(3)を満たす必要がある。
Mw/Mn≦0.030×Ln(v)+1.010 (但し、v<10)(2)
Mw/Mn≦−0.026×Ln(v)+1.139(但し、v≧10)(3)
これらの式で、Ln(v)はvの自然対数を意味し、vは脂肪族系アルコール(a1)1モル当たりに付加したアルキレンオキサイドの平均付加モル数を表し、前記一般式(1)でのアルキレンオキサイドの付加モル数であるkの平均に相当する。(以下同じ)
関係式(2)または(3)を満たさない、すなわち分子量分布が広くなると、アニオン性界面活性剤としたときに、充分な界面活性能が得られない。
また、Mw/Mnは下記関係式(2’)または(3’)を満たすことが好ましい。
Mw/Mn≦0.031×Ln(v)+1.000 (但し、v<10)(2’)
Mw/Mn≦−0.026×Ln(v)+1.129(但し、v≧10)(3’)
【0016】
一般式(1)においてAがエチレン基のみである場合、即ち、脂肪族系アルコール(a1)にエチレンオキサイドのみを付加した場合には、重量平均分子量(Mw)と数平均分子量(Mn)との比:Mw/Mnが関係式(2)または(3)に代わって、下記(6)または(7)を満たすことが好ましい。
Mw/Mn≦0.020×Ln(v)+1.010 (但し、v<10)(6)
Mw/Mn≦−0.026×Ln(v)+1.116(但し、v≧10)(7)
関係式(6)または(7)を満たす場合、即ち分子量分布が狭くなると、アニオン性界面活性剤としたときに、良好な界面活性能が得られる。
また、この場合、Mw/Mnは下記関係式(6’)または(7’)を満たすことがさらに好ましい。
Mw/Mn≦0.018×Ln(v)+1.015 (但し、v<10) (6’)
Mw/Mn≦−0.023×Ln(v)+1.113(但し、v≧10)(7’)
【0017】
さらに、(A)は、下記Weibullの分布則の式(8)から導き出される関係式(4)から分布定数cを求めることができるとき、cが2.0以下である必要がある。cは好ましくは1.0以下、さらに好ましくは0.7以下である。関係式(4)において、分布定数cの値が小さい、すなわち未反応の脂肪族系アルコールの含有量が少ないほど分子量分布が狭いことを意味する。
なお、この式は、未反応の脂肪族系アルコール(a1)の量が検出限界(0.001質量%)以上の場合に適用される式であり、(A)の場合はアルキレンオキサイド(b1)の平均付加モル数が12モル程度まで適用可能である。
cが2を超えると、アニオン性界面活性剤としたときに、充分な界面活性能が得られない。
v=c×Ln(n00/n0)−(c−1)×(1−n0/n00) (8)
c=(v+n0/n00−1)/[Ln(n00/n0)+n0/n00−1] (4)
これらの式で、Ln(n00/n0)は(n00/n0)の自然対数を意味し、vは上記に同じ、n00は反応に用いた脂肪族系アルコール(a1)のモル数、n0 は未反応の脂肪族系アルコール(a1)のモル数を表す。
【0018】
本発明において、上記(A)としては、さらに下記一般式(1’)で表される化合物であることが、起泡力の点で好ましい。
R1−[(OC2H4)m/(OD)n]−(OC2H4)p−OH (1’)
[式中、R1 は炭素数8〜24の脂肪族炭化水素基または炭素数8〜24の脂環式炭化水素基;Dは炭素数3または4のアルキレン基;mは平均が0〜5となる0または1以上の整数、nは平均が0〜5となる0または1以上の整数、pは平均が1〜10となる0または1以上の整数であり、(m+n+p)は平均が1〜20となる整数であり、(m+p)/(m+n+p)は平均0.5以上である。{(OC2H4)m/(0D)n}は、m≠0,n≠0のときブロック付加またはランダム付加を表す。]
【0019】
上記一般式(1’)中、(OC2H4)の部分は、EOの付加により形成される。Dは炭素数3または4のアルキレン基を表し、(OD)の部分は、炭素数3または4のアルキレンオキサイドの付加により形成される。このようなアルキレンオキサイドとしては、PO、1,2−もしくは2,3−ブチレンオキサイドなどが挙げられる。
【0020】
上記一般式(1’)中、mは平均が0〜5となる0または1以上の整数であり、さらに好ましくは0〜3の整数である。nは平均が0〜5となる0または1以上の整数であり、さらに好ましくは0または1である。pは平均が1〜10となる0または1以上の整数であり、さらに好ましくは1〜8である。(m+n+p)は平均が1〜20の整数であり、さらに好ましくは1〜12である。(m+p)/(m+n+p)は平均0.5以上であり、さらに好ましくは0.7以上である。0.5以上であると、アニオン性活性剤としたときの洗浄力が良好となる。{(OC2H4)m/(OD)n} の部分は、ブロック付加〔(OC2H4)m、(OD)nの順〕 でもランダム付加でもよいが、さらに好ましくはブロック付加である。
【0021】
本発明において、(A)としては、以下に述べる方法により製造された(A1)または(A2)であることが好ましい。
すなわち、前記の、Weibullの分布則から導かれる式(4)から求められる分布定数cが2.0以下となる付加物を与える触媒(d)の存在下、前記脂肪族系アルコール(a1)にアルキレンオキサイド(b2)を平均1〜2.5モル付加して得られる脂肪族系アルコールアルキレンオキサイド付加物(A1)であるか、(A1)にさらにアルカリ触媒(f)の存在下でアルキレンオキサイド(b3)を付加反応させてなる脂肪族系アルコールアルキレンオキサイド付加物(A2)であるのが好ましい。さらに好ましくは(A2)である。
【0022】
上記アルキレンオキサイド(b2)および(b3)としては、炭素数2以上のアルキレンオキサイドが挙げられる。具体例としては、一般式(1)におけるOAを形成するアルキレンオキサイド(b1)の例として前記したアルキレンオキサイドが挙げられ、2種以上を併用してもよい。2種以上用いる場合は、ブロック付加でもランダム付加でもよいが、好ましくはブロック付加である。これらのうちで好ましくは、EOおよび/またはPOである。
【0023】
触媒(d)としては、得られるアルキレンオキサイド付加物の分布定数cが2.0以下となるものを用いる。好ましくはcが1.0以下、さらに好ましくは0.7以下、特に好ましくは0.45以下となるものである。分布定数cが2.0を超えるものを用いると、アニオン性界面活性剤とした場合に、低温でカスミを生じたり、起泡性、洗浄性が低下する。また、皮膚に対する刺激性が低くならず、問題となることがある。
【0024】
触媒(d)の具体例としては、過ハロゲン酸もしくはその塩、硫酸塩、燐酸塩および硝酸塩が挙げられる。塩を形成する場合の金属は、特に限定されるものではないが、アルカリ金属以外のものが好ましく、2価または3価の金属が好ましい。
これら金属として好ましくは、Mg、Ca、Sr、Ba、Zn、Co、Ni、Cu、Alであり、より好ましくは、Mg、Zn、Ca、Sr、Ba、Alであり、特に好ましくは、Mg、Zn、Alである。過ハロゲン酸(塩)のハロゲンとしては塩素、臭素、沃素が挙げられ、塩素が好ましい。

【0026】
(a1)に(b2)を付加して得られるアルキレンオキサイド付加物(A1)に、アルキレンオキサイド(b3)を付加させる際に用いる触媒は、アルカリ触媒(e)である。

触媒(e)の使用量としては、反応速度と経済性の点から、(A1)と(b3)の合計100質量部当たり、0.0001〜1質量部が好ましい。さらに好ましくは0.001〜0.8質量部である。
【0027】
(a1)と(b2)を反応させる場合の反応条件としては、(a1)と(d)を混合し、窒素置換を行った後、−0.8〜5kgf/cm2 Gで、80〜200℃で(b2)を導入し、所定量の(b2)を投入後、80〜200℃で反応系内の圧力が平衡になるまで熟成を行う方法などが挙げられる。
このようにして得られたアルキレンオキサイド付加物(A1)に、アルカリ触媒(e)を添加し、アルキレンオキサイド(b3)を、上記と同様の方法で反応することで、脂肪族系アルコールアルキレンオキサイド付加物(A2)が得られる。
【0028】
(A)からスルホコハク酸エステル塩(B)を得る方法は、特に限定されないが、一例としては、(A)と無水マレイン酸(以下MAと略記することがある)を反応させてエステル化物を得る工程と、水の存在下、亜硫酸塩や酸性亜硫酸塩を用いスルホン化する工程との二段工程で反応する方法が挙げられる。
