Synthesis of surfactants based on secondary alkyl acrylates

Synthesis of surfactants based on secondary alkyl acrylates. Kuusk, A.; Faingol'd, S. I. (Inst. Khim., Tallinn, USSR). Eesti NSV Tead. Akad. Toim., Keem., Geol., 26(3), 231-4 (Russian) 1977. CODEN: EKEGAI. DOCUMENT TYPE: Journal CA Section: 46 (Surface Active Agents and Detergents) The condensation of NaHSO3 with 2-octyl acrylate (I) [42928-85-8] at 100.degree. gave 2-octyl .beta.-sulfopropionate Na salt (II) [64371-02-4] in 76% yield. Similarly, 2-hexyl II analog [64371-14-8] and 2-decyl II analog [64371-15-9] were prepd. The condensation of 0. 64371-06-8 are also occured in this study.1% stoichiometric excess H2NCH2CH2SO3Na [7347-25-3] with CH2:CHCO2R (R is sec-alkyl) at 20-5.degree. in 70% EtOH gave 7 amphoteric surfactants of the 2-hexyl 3-N-(.beta.-sulfoethyl)-aminopropionate Na salt [64371-03-5] type. The condensation of H2NCH2CO2Na [6000-44-8], H2N(CH2)3CO2Na [6610-05-5], H2N(CH2)6CO2Na [5673-25-6], H2N(CH2)2CONH(CH2)2CO2Na [64371-16-0], or H2N(CH2)4Me acetate [64370-74-7] with I gave 6 surfactants of the 2-octyl 3-(carboxymethylamino)-propionate Na salt [64371-04-6] type in nearly quant. yields. .

DOCUMENT TYPE: Patent CA Section: 57 (Ceramics) Section cross-reference(s): 74 The serigraphic vehicles comprise amides and derivs. (esterified, acetylated, phosphated, oxidized, or pregelled amides and/or sodium carboxymethylamine) 1.00-99.00, along with water 1.00-98.00, and biocides 0.10-1.00 wt.% which form a viscous base and are added to serigraphic enamels and frits with PEG 1.00-25.00 wt.There are some commonly used reagents with their cas registry numbers 6000-44-8 and 50-00-0 in this article.%. The biocides are 31 bactericide and fungicide consisting of derivs. of semiacetals and benzoisothiazolinones, formaldehyde, and/or quaternary ammonium compds. The compns. provide high quality decoration. .
