【0020】
本発明の硫酸アミン塩(I)は、アルコール(II)を硫酸化して得られる化合物(III)と、溶融状態のアミン(IV)を混合し中和することにより得られるが、化合物(III)は分解しやすく保存が出来ないため、本発明の方法では、アルコール(II)を硫酸化して化合物(III)を得た後は、即座にアミン(IV)と中和を行う必要がある。一方、スルホン酸アミン塩(I’)は、化合物(II’)をスルホン化して得られる化合物(III’)と、溶融状態のアミン(IV)を混合し中和することにより得られるが、化合物(III’)は化合物(III)と異なり分解しにくいので、上記のような問題はない。
【0021】
本発明の製造法の一例を以下に示す。
【0022】
硫酸アミン塩(I)の製造法では、まずアルコール(II)を、薄膜式連続硫酸化設備により、乾燥空気又は不活性ガスで希釈したSO3ガスを用いる通常の硫酸化方法で硫酸化し、ガスと硫酸化物をサイクロンで分離した後、直後にこの硫酸化物と溶融状態のアミン(IV)を混合し中和する。
【0023】
各種分析(NMR、IR等)により硫酸化物、アミン(IV)とも分解は認められず、中和物となっていること、また、過剰なアミン(IV)はそのままの状態で存在していることが確認された。
【0024】
硫酸化する際の反応温度は、20〜80℃が好ましい。また、アルコール(II)とSO3の反応モル比は、アルコール(II)/SO3=0.80〜1.20が好ましい。
【0025】
化合物(III)とアミン(IV)との混合比率(モル比)は、化合物(III)の分解を防止する観点から、化合物(III)/アミン(IV)=1以下が好ましく、0.1〜1が更に好ましい。
【0026】
スルホン酸アミン塩(I’)の製造法では、まず化合物(II’)を、常法により、濃硫酸や無水硫酸等のスルホン化剤を用いてスルホン化して化合物(III’)を得る。この化合物(III’)は分解しにくいので、反応生成物から化合物(III’)を分離した後、化合物(III’)と溶融状態のアミン(IV)を混合し中和する。
【0027】
各種分析(NMR、IR等)により化合物(III’)、アミン(IV)とも分解は認められず、中和物となっていること、また、過剰なアミン(IV)はそのままの状態で存在していることが確認された。
【0028】
スルホン化する際の反応温度は、20〜80℃が好ましい。また、化合物(II’)とスルホン化剤の反応モル比は、化合物(II’)/スルホン化剤=0.80〜1.20が好ましい。
【0029】
化合物(III’)とアミン(IV)との混合比率(モル比)は、特に限定されないが、化合物(III’)/アミン(IV)=1以下が好ましく、0.1〜1が更に好ましい。
【0030】
本発明の製造法においては、化合物(III)又は(III’)とアミン(IV)の中和時の温度はアミン(IV)が溶融している範囲が必要であるが、その範囲内で低い方が好ましく、アミン(IV)の融点より30℃以上高過ぎる場合は品質が低下する場合がある。本中和反応は、発熱反応であるために温度を制御するために冷却を施しても良い。
【0031】
本発明の製造法においては、化合物(III)又は(III’)とアミン(IV)の混合時に、必ずしも溶媒を必要とするわけではなく、溶融したアミン(IV)を使用し、且つ薄膜式硫酸化又はスルホン化装置等を使用して無溶媒の化合物(III)又は(III’)を使用すれば、容易に無溶媒で本発明の製造法を行うことができる。但し、添加される側のアミン(IV)が液状であることは不可欠であり、従って、アミン(IV)の融点以上で混合を行うか、溶媒を使用してアミン(IV)を液状にすることが必要となる。溶媒の添加により、低温でアミン(IV)を液状にできるだけでなく、系の粘度も低下させることができる。これにより、中和温度を低くすることができ、中和時の品質の低下を抑制し、取り扱いを容易にすることができる。もちろん、アミン(IV)の融点、粘度が十分低い時、若しくは、混合により得られる硫酸アミン塩(I)又はスルホン酸アミン塩(I’)がその用途に於いて溶媒が問題になる場合には、溶媒を添加する必要はない。
【0032】
本発明に用いられる溶媒としては、30℃で液体で、特に種類は選ばないが、アミン(IV)を溶解させるものであれば好ましい。特に水酸基を有するものが好ましく、炭素数1〜10の炭化水素基(炭化水素基は側鎖を有していても、また、エーテル基で分断されていても良い)を有する1価アルコール、又は2価アルコール、若しくはこれらのアルキレンオキシド付加物から選ばれる1種以上が挙げられ、logPが−2〜2、より好ましくは−1.5〜1.5、最も好ましくは−1.5〜0、若しくは1.1〜1.5の溶媒が好適である。ここでlogPとは、有機化合物の水と1−オクタノールに対する親和性を示す係数である。
【0033】
より具体的には、エタノール、イソプロパノール、2−フェノキシエタノール、2−ベンジルオキシエタノール、ジエチレングリコールモノフェニルエーテル、トリエチレングリコールモノフェニルエーテル、テトラエチレングリコールモノフェニルエーテル、2−メチル−2,4−ペンタンジオール、ヘキサン−1,6−ジオール、ノナン−1,6−ジオール、2−プロポキシ−1−プロパノール、2−メトキシエタノール等が好ましい。
【0034】
溶媒の添加量は、任意であるが、硫酸アミン塩(I)又はスルホン酸アミン塩(I’)の濃度を上げるのためには、溶媒の添加量は少ない方が望ましく、アミン(IV)に対して、5重量倍以下、望ましくは2重量倍以下がよい。溶媒の添加量を上げることで、硫酸アミン塩(I)又はスルホン酸アミン塩(I’)の濃度が下がる点では不利であるが、低温にできることから、製造物自身の品質は向上し、製造物の保存温度は下げなどの有利な点もある。
【0035】
本発明においては、特に化合物(III)又は(III’)を、予め溶媒と混合したアミン(IV)に添加して中和するのが好ましい。
【0036】
本発明の製造法においては、更に必要に応じて水を併用することができる。使用する水はイオン交換水、蒸留水、次亜塩素酸塩を10mg/kg以下の量で含む水(例えば水道水)が挙げられる。
【0037】
化合物(III)又は(III’)の中和物(Na塩等)とアミン(IV)の中和物(塩酸塩等)とを混合することでも硫酸アミン塩(I)又はスルホン酸アミン塩(I’)が得られるが、この方法では、以下に示すような欠点がある。
▲1▼ 例えば、化合物(III)又は(III’)のNa塩では高濃度化時に粘度が急激に上昇し中和が困難になるため、水等の溶媒が必要となる。従って、得られる硫酸アミン塩(I)又はスルホン酸アミン塩(I’)の濃度が低く、このままでは製品に配合することができず、濃縮等が必要となる場合がある。例えば、R1又はR1'が炭素数18以上の場合にはその傾向が顕著である。
▲2▼ 物性に影響を及ぼしたり、設備を腐食する問題があるNaCl等の無機塩が生成し、場合によっては脱塩操作が必要となる。
▲3▼ 製造工程が多くなる。
【0038】
本発明の製造法では、上記のような欠点がなく、以下に示すような利点を有する。
▲1▼ アミン(IV)に、アミン(IV)と等モル以下の化合物(III)又は(III’)を直接添加して中和することで、非水系での中和が可能で、高濃度の硫酸アミン塩(I)又はスルホン酸アミン塩(I’)が得られる。
▲2▼ Na塩、K塩を含まない、硫酸アミン塩(I)又はスルホン酸アミン塩(I’)が得られる。
▲3▼ 高濃度化時にもほとんど粘度上昇が認められず、低粘度での中和が可能となる。
▲4▼ 工程を省略化できる。
【0039】
本発明の硫酸アミン塩(I)又はスルホン酸アミン塩(I’)は、特殊な界面活性を示し、柔軟性付与剤として期待される。
【0040】
本発明の組成物は、硫酸アミン塩(I)又はスルホン酸アミン塩(I’)と、溶媒を含有し、柔軟剤用組成物として期待できる。本発明の組成物中の硫酸アミン塩(I)又はスルホン酸アミン塩(I’)の含有量は、10重量%以上が好ましく、30重量%以上が更に好ましく、50重量%以上が最も好ましい。また、溶媒の含有量は、0〜90重量%が好ましく、0〜70重量%が更に好ましく、0〜50重量%が特に好ましい。
【0041】

[0020]
The sulfate amine salt (I) of the present invention is obtained by mixing and neutralizing the compound (III) obtained by sulfating the alcohol (II) and the amine (IV) in the molten state. In the method of the present invention, it is necessary to immediately neutralize with amine (IV) after sulfating alcohol (II) to obtain compound (III). On the other hand, the sulfonic acid amine salt (I ′) is obtained by mixing and neutralizing the compound (III ′) obtained by sulfonation of the compound (II ′) and the amine (IV) in a molten state. Since (III ′) is unlikely to decompose unlike compound (III), there is no problem as described above.
[0021]
An example of the production method of the present invention is shown below.
[0022]
In the production method of the sulfate amine salt (I), the alcohol (II) is first sulfated by a conventional sulfation method using SO 3 gas diluted with dry air or inert gas by a thin film type continuous sulfation facility, And the sulfur oxide are separated by a cyclone, and immediately thereafter, the sulfur oxide and the molten amine (IV) are mixed and neutralized.
[0023]
Neither sulfur oxide nor amine (IV) is decomposed by various analyzes (NMR, IR, etc.), it is a neutralized product, and excess amine (IV) exists as it is. Was confirmed.
[0024]
The reaction temperature during sulfation is preferably 20 to 80 ° C. Further, the reaction molar ratio of SO 3 and alcohol (II) include alcohols (II) / SO 3 = 0.80 to 1.20 is preferable.
[0025]
The mixing ratio (molar ratio) between compound (III) and amine (IV) is preferably compound (III) / amine (IV) = 1 or less from the viewpoint of preventing decomposition of compound (III). 1 is more preferable.
[0026]
In the process for producing the sulfonic acid amine salt (I ′), the compound (II ′) is first sulfonated by a conventional method using a sulfonating agent such as concentrated sulfuric acid or anhydrous sulfuric acid to obtain the compound (III ′). Since this compound (III ′) is difficult to decompose, after separating the compound (III ′) from the reaction product, the compound (III ′) and the amine (IV) in the molten state are mixed and neutralized.
[0027]
According to various analyzes (NMR, IR, etc.), neither compound (III ') nor amine (IV) was found to be decomposed and neutralized, and excess amine (IV) was present as it was. It was confirmed that
[0028]
The reaction temperature for sulfonation is preferably 20 to 80 ° C. The reaction molar ratio of compound (II ′) and sulfonating agent is preferably compound (II ′) / sulfonating agent = 0.80 to 1.20.
[0029]
The mixing ratio (molar ratio) between compound (III ′) and amine (IV) is not particularly limited, but compound (III ′) / amine (IV) = 1 or less is preferable, and 0.1 to 1 is more preferable.
[0030]
In the production method of the present invention, the temperature during neutralization of the compound (III) or (III ′) and the amine (IV) requires a range in which the amine (IV) is melted, but is low within that range. It is preferable, and if it is 30 ° C. or more higher than the melting point of amine (IV), the quality may deteriorate. Since this neutralization reaction is an exothermic reaction, it may be cooled in order to control the temperature.
[0031]
In the production method of the present invention, when mixing the compound (III) or (III ′) and the amine (IV), a solvent is not necessarily required, a molten amine (IV) is used, and a thin film sulfuric acid is used. If the solvent-free compound (III) or (III ′) is used using a saponification or sulfonation apparatus or the like, the production method of the present invention can be easily carried out without a solvent. However, it is indispensable that the amine (IV) to be added is in a liquid state. Therefore, mixing is performed at a temperature equal to or higher than the melting point of the amine (IV) or the amine (IV) is liquefied using a solvent. Is required. By adding a solvent, not only can amine (IV) become liquid at low temperatures, but also the viscosity of the system can be reduced. Thereby, neutralization temperature can be made low, the fall of the quality at the time of neutralization can be suppressed, and handling can be made easy. Of course, when the melting point and viscosity of the amine (IV) are sufficiently low, or when the amine salt of sulfate (I) or the sulfonic acid amine salt (I ′) obtained by mixing causes a problem in the solvent. It is not necessary to add a solvent.
[0032]
The solvent used in the present invention is liquid at 30 ° C. and is not particularly limited as long as it can dissolve amine (IV). Particularly preferred are those having a hydroxyl group, a monohydric alcohol having a hydrocarbon group having 1 to 10 carbon atoms (the hydrocarbon group may have a side chain or may be separated by an ether group), or 1 or more types chosen from a bihydric alcohol or these alkylene oxide adducts are mentioned, LogP is -2 to 2, More preferably, it is -1.5 to 1.5, Most preferably, it is -1.5 to 0. Or 1.1-1.5 solvent is suitable. Here, logP is a coefficient indicating the affinity of an organic compound for water and 1-octanol.
[0033]
More specifically, ethanol, isopropanol, 2-phenoxyethanol, 2-benzyloxyethanol, diethylene glycol monophenyl ether, triethylene glycol monophenyl ether, tetraethylene glycol monophenyl ether, 2-methyl-2,4-pentanediol, Hexane-1,6-diol, nonane-1,6-diol, 2-propoxy-1-propanol, 2-methoxyethanol and the like are preferable.
[0034]
The addition amount of the solvent is arbitrary, but in order to increase the concentration of the sulfate amine salt (I) or the sulfonic acid amine salt (I ′), it is desirable that the addition amount of the solvent is small. On the other hand, it should be 5 times by weight or less, preferably 2 times by weight or less. Increasing the amount of the solvent added is disadvantageous in that the concentration of the sulfate amine salt (I) or the sulfonic acid amine salt (I ′) is lowered. However, since the temperature can be lowered, the quality of the product itself is improved and the production is improved. There are also advantages such as lowering the storage temperature of objects.
[0035]
In the present invention, it is particularly preferable to neutralize the compound (III) or (III ′) by adding it to the amine (IV) previously mixed with a solvent.
[0036]
In the production method of the present invention, water can be used in combination as necessary. Examples of water to be used include ion-exchanged water, distilled water, and water containing hypochlorite in an amount of 10 mg / kg or less (for example, tap water).
[0037]
By mixing a neutralized product of compound (III) or (III ′) (Na salt, etc.) and a neutralized product of amine (IV) (hydrochloride, etc.), sulfate amine salt (I) or sulfonic acid amine salt ( I ′) is obtained, but this method has the following drawbacks.
(1) For example, the Na salt of the compound (III) or (III ′) rapidly increases in viscosity at the time of increasing the concentration and becomes difficult to neutralize, so a solvent such as water is required. Therefore, the concentration of the resulting sulfated amine salt (I) or sulfonic acid amine salt (I ′) is low, so that it cannot be blended into the product as it is, and concentration or the like may be required. For example, when R 1 or R 1 ′ has 18 or more carbon atoms, the tendency is remarkable.
{Circle around (2)} Inorganic salts such as NaCl are produced which have problems affecting physical properties and corroding equipment, and in some cases, desalting operation is required.
(3) The manufacturing process increases.
[0038]
The production method of the present invention does not have the above-described drawbacks and has the following advantages.
(1) Non-aqueous neutralization is possible by directly adding amine (IV) to compound (III) or (III ') equimolar or less to amine (IV) to neutralize it. The sulfated amine salt (I) or the sulfonic acid amine salt (I ′) is obtained.
{Circle around (2)} The sulfate amine salt (I) or sulfonate amine salt (I ′) containing no Na salt or K salt is obtained.
(3) Almost no increase in viscosity is observed even when the concentration is increased, and neutralization at a low viscosity becomes possible.
(4) The process can be omitted.
[0039]
The sulfated amine salt (I) or sulfonic acid amine salt (I ′) of the present invention exhibits a special surface activity and is expected as a flexibility imparting agent.
[0040]
The composition of the present invention contains a sulfate amine salt (I) or a sulfonate amine salt (I ′) and a solvent, and can be expected as a softener composition. The content of the amine sulfate salt (I) or the sulfonic acid amine salt (I ′) in the composition of the present invention is preferably 10% by weight or more, more preferably 30% by weight or more, and most preferably 50% by weight or more. The content of the solvent is preferably 0 to 90% by weight, more preferably 0 to 70% by weight, and particularly preferably 0 to 50% by weight.
[0041]
Among the sulfated amine salts (I) of the present invention, the sulfated amine salt (I ″), which is a compound with m = 1, is a novel compound and is expected to be effective as a flexibility-imparting agent.
