The obtained water meets the parameters of the Brazilian Pharmacopoeia and can be used in chemical laboratories in substitution to that obtained in the electric distillers. / Este trabalho propôs a utilização de um destilador que emprega a energia solar para a produção de água destilada própria para o uso em laboratórios de análise química da Universidade Federal de Goiás (UFG). A escolha do destilador solar se deve à alta incidência de radiação solar no Brasil, e por este tipo de equipamento não consumir energia elétrica, não gerar desperdício de água potável, ser de fácil operação e requerer baixa tecnologia.Desenvolveu-se um estudo sobre a intensidade da radiação incidente no período de inverno seco e verão úmido dos municípios de Catalão, Goiânia e Jataí, onde estão localizados os campus desta universidade, baseado no modelo de Duffie e Beckman (2013). A partir dos dados gerados de radiação foi possível determinar do que 20º seria o melhor ângulo para a cobertura do equipamento, assim o modelo piloto foi construído e instalado no Instituto de Química da UFG na cidade de Goiânia. Com os dados experimentais de temperaturada água (Tw) e da cobertura do destilador (Tg) registrados de hora em hora (das 8 h às 18 h), pôde-se realizar o balanço de energia do destilador, fundamentado no modelo de Dunkle (1961),pelo qual foram calculados os coeficientes de transferência de calor por convecção (hcw) e por evaporação (hew), as taxas de transferência de calor por convecção (qcw) e por evaporação (qew), a taxa de transferência de massa ( ew) e a eficiência do destilador (ηi). Os resultados obtidos permitiram concluir que o coeficiente de transferência de calor por evaporação e sua taxa correspondente foram maiores do que coeficiente de transferência de calor porpor convecção e sua respectiva taxa. A produção de água destilada no inverno e no verão foram de 0,31 e 1,51 kgm-2dia-1, respectivamente e a eficiência máxima do destilador foi de 5,4% no inverno e 41,33% no verão. A água obtida atende aos parâmetros da Farmacopéia Brasileira e pode ser utilizada em laboratórios químicos em substituição à obtida nos destiladores elétricos.

The subject of graduation theses is the facture of the enterpreneurial plan of succesor company Oleochem a.s. First part is engaged in the enterpreneurial plan in theoretical line and in the process of company's restructuralisation. The practical part of graduation theses creates the historical review of the development of company SETUZA a.s. including the process of its restructuralisation. The last part of work consists of chapters, which are engaged in organization structure, products, competitive environment, production, the purchase of raw materials, quality and financial plan. At the close of graduation theses are introduced the strong and weak spots, the risks and the opportunities of enterpreneurial plan.

This master´s thesis deals about insulation and dielectric properties of water. It describes the structure of water, covalent and hydrogen bonds. It outlines primary chemical and physical properties of water and then it describes parameters of water - dynamic viscosity, conductivity, surface tension, pH and also describes dielectric properties - dielectric loss, loss factor, permittivity, polarization. Part of the work is practical section, which includes measurements of deionized water, destilled water, tap water and shows primary dependence such as dependence loss factor on frequency or relative permittivity on frequency.
