A polymer containing vinyl acetate as a main component and higher fatty acid vinyl ester as a subcomponent is added to and mixed with a liquid hydrocarbon containing alcohol or hydrous alcohol. This invention relates to a method for stabilizing liquid hydrocarbons.

知である。例えば、メタノールは常温でガソリン
中に10％は容易に混合し、混合ガソリンとして用
いられている。 It is known that alcohol is mixed uniformly with liquid hydrocarbons to some extent and is used as a gas hole. For example, 10% methanol is easily mixed into gasoline at room temperature and is used as mixed gasoline.
しかしながら、これらアルコール含有の液状炭
化水素は少量の水の混入によりアルコール、水が
液状炭化水素より分離し二層に別れるのも公知で
ある。 However, it is also known that when these alcohol-containing liquid hydrocarbons are mixed with a small amount of water, the alcohol and water are separated from the liquid hydrocarbon and separated into two layers.

るとは言い難い。 The unstable properties of alcohol-containing liquid hydrocarbons, as typified by this property, have greatly reduced the uses of this mixture. As a method for removing this defect, methods of mixing not only methanol and ethanol but also higher alcohols or ethers have been studied, but it cannot be said that this defect has been fundamentally improved. On the other hand, attempts are being made to solve this problem by using surfactants, but it cannot be said that this field has been completely solved yet.

達せられる。 The present invention effectively improves the properties of alcohol-containing liquid hydrocarbons, which have poor stability. Polymers containing alcohol as a main component and vinyl acetate as a subcomponent, or "polymer containing vinyl alcohol as a main component and vinyl acetate as a subcomponent, with the vinyl alcohol content adjusted so that it is soluble in alcohol and has an affinity for water." ``A polymer containing vinyl acetate as a main component and a higher fatty acid vinyl ester as a minor component, which is alcohol-soluble and whose higher fatty acid content has been adjusted to have an affinity for liquid hydrocarbons.'' This can be achieved by adding and mixing both of them to an alcohol-containing liquid hydrocarbon.

潤性を示す重合物を言う。 Here, "a polymer containing vinyl alcohol as a main component and vinyl acetate as a subcomponent, the vinyl alcohol content of which has been adjusted so that it is alcohol-soluble and has an affinity for water" refers to ethylene-vinyl acetate-vinyl alcohol. Polymers whose main component is vinyl alcohol, such as copolymers and partially saponified polyvinyl acetate, which are soluble in alcohol and insoluble in water but exhibit swelling properties; "Polymer containing vinyl acetate as a main component and higher fatty acid vinyl ester as a minor component, whose higher fatty acid content has been adjusted to have an affinity for hydrocarbons" is an ethylene-vinyl acetate-higher fatty acid vinyl copolymer. Polymers mainly composed of vinyl acetate, such as vinyl acetate-higher fatty acid vinyl copolymers, are soluble in alcohols, insoluble in liquid hydrocarbons, and exhibit some swelling properties.
本来、重合物はその化学組成のみでなく、重合

モノマー基のモル比、配列状態、その他により性
質が大巾に変わることは周知である。 It is well known that the properties of polymers vary widely depending not only on their chemical composition, but also on the degree of polymerization, degree of polymerization distribution, degree of branching, and in the case of copolymers, the molar ratio of each monomer group, arrangement state, and other factors. It is.

能を見出した場合に於ては、その重合物の規定に

ことがより妥当な方法であると考えられる。 Therefore, when a new function is discovered in the properties of a polymer as in the present application, the definition of the polymer does not primarily include the chemical composition but also the structure of the polymer. It is thought that a more appropriate method would be to include the properties themselves in the specifications.

が、一般的には予めこれらの重合物をアルコール
に溶解しておき、徐々に液状炭化水素を添加して
行く方法が好ましい。 Regarding stabilization, these polymers may be added directly to a mixture of alcohol and liquid hydrocarbon, but generally these polymers are dissolved in alcohol in advance and liquid hydrocarbon is gradually added. The preferred method is to do so.

溶化しているのではないかと思われる。 As the alcohol, various alcohols such as methanol and ethanol propanol can be used, and mixtures thereof may also be used. Further, as a feature of this method, this alcohol system may contain some water. The mechanism by which alcohol-containing liquid hydrocarbons are stabilized by adding one or two of the above polymers according to the present invention is not necessarily clear, but the affinity of liquid hydrocarbons with methanol, for example, is due to the addition of these polymers. increased due to
As shown in JP-A No. 54-068371, the cause is thought to be, for example, methanol being solubilized in liquid hydrocarbons. Also, it seems that even if water is added to this system, it is emulsified and solubilized.
