Embodiment

[0092] Hereinafter, the present invention will be specifically described based on examples. In addition, unless otherwise indicated in the table|surface, content of each component shows mass %. In addition, the measurement methods of various physical properties are as follows.

[0093] (1) Measurement conditions

[0094] (i) Determination method of double bond position of internal olefin

[0095] The double bond positions of internal olefins are determined by gas chromatography (hereinafter abbreviated as GC). Specifically, after producing a disulfide derivative by reacting dimethyl disulfide with an internal olefin, each component was separated by GC. The position of the double bond of the internal olefin was determined from the area of ​​each peak.

[0096] In addition, the apparatus and analysis conditions used for the measurement are as follows. GC device (trade name: HP6890, manufactured by HEWLETT PACKARD Co.), column (trade name: Ultra-Alloy-1HT capillary column 30...

manufacture example A

[0112] [Production Example A] Synthesis of internal olefin with 16 carbon atoms and 16.5% by mass of 2-position double bond

[0113] Add 7000 g (28.9 moles) of 1-hexadecanol (product name: Kalcol 6098, manufactured by Kao Corporation) and 700 g of solid acid catalyst γ-alumina (STREM Chemicals, Inc.) (relative to Raw material alcohol (10% by mass) was reacted at 280° C. for 5 hours while blowing nitrogen gas (7000 mL / min.) into the system under stirring conditions. After the reaction, the conversion rate of alcohol was 100%, and the purity of C16 internal olefins was 99.7%. The obtained crude internal olefins were transferred to a distillation flask and distilled at 136-160° C. / 4.0 mmHg to obtain internal olefins having 16 carbon atoms with an olefin purity of 100%. The double bond distribution of the obtained internal olefin was: 0.5% by mass at the C1 position, 16.5% by mass at the C2 position, 15.4% by mass at the C3 position, 16.4% by mass at the C4 position, 17.2% by mas...

manufacture example B

[0114] [Production Example B] Synthesis of internal olefin with 18 carbon atoms and 16.9% by mass of 2-position double bond

[0115] Add 1-octadecyl alcohol (product name: Kalcol 8098, manufactured by Kao Corporation) 7000g (25.9 moles) and solid acid catalyst γ-alumina (STREM Chemicals, Inc) 1050g (relatively The raw material alcohol was 15% by mass), and reacted for 13 hours at 285° C. while flowing nitrogen gas (7000 mL / min.) into the system while stirring. After the reaction, the conversion rate of alcohol was 100%, and the purity of C18 internal olefins was 98.5%. The obtained crude internal olefin was transferred to a distillation flask and distilled at 148-158° C. / 0.5 mmHg to obtain an internal olefin having 18 carbon atoms with an olefin purity of 100%. The double bond distribution of the obtained internal olefin was 0.7% by mass at the C1 position, 16.9% by mass at the C2 position, 15.9% by mass at the C3 position, 16.0% by mass at the C4 position, 14.7% by mass at t...

Abstract

Provided is an internal olefin sulfonate composition that can achieve at high levels excellent foamability, foaming amount, rapid-foaming, foam disappearance, foam quality, foam persistence in the presence of sebum, and foam quantity in the presence of sebum; also provided is a detergent composition containing said internal olefin sulfonate composition. This internal olefin sulfonate composition contains (A) an internal olefin sulfonate having a carbon number of 16 and/or (B) an internal olefin sulfonate having a carbon number of 18. The total content of component (A) and component (B) is 50-100 mass%, the content ratio (A/B) of component (A) and component (B) is 0/100-70/30, and the content of internal olefin sulfonates having a sulfonic acid group in position 2 is 25 mass% or less. The mass ratio of the content of hydroxy bodies in the internal olefin sulfonates of component (A) and component (B) and the content of olefin bodies in the internal olefin sulfonates of component (A) and component (B) (hydroxy bodies / olefin bodies) is 75/25-100/0.

Description

technical field [0001] The present invention relates to an internal olefin sulfonate composition useful as a detergent base and a detergent composition containing the same. Background technique [0002] Conventionally, anionic surfactants, especially alkyl sulfates and alkyl polyoxyalkylene sulfates have been widely used as household and industrial cleansing components because of their excellent detergency and foaming power. As one of the anionic surfactants, olefin sulfonates, especially internal olefin sulfonates obtained from internal olefins (where the double bond is not at the end of the olefin chain but inside) are reported. [0003] Such an internal olefin sulfonate is generally obtained by reacting an internal olefin with a gas containing gaseous sulfur trioxide for sulfonation, neutralizing the obtained sulfonic acid, and further hydrolyzing it. This internal olefin sulfonate is known to be good in biodegradability, etc., but it is generally used in common with alk...
