DL-Tartaric acid is a water- and alcohol-soluble colorless crystalline solid with a characteristic acid taste and a melting temperature of 170\u00b0C(338\u00b0F). Naturally occurring tartaric acid is generally of the L-configuration (based on the absolute configuration of D-glyceric acid). The L-forms of tartrates are dextrorotatory in solution and thus are designated as L(+)-tartrates. It is also known as dihydroxy succinic acid. Tartaric acid is used as a chemical intermediate and a sequestrant,as well as in tanning, effervescent beverages, baking powder, ceramics, photography, textile processing,mirror silvering,and metal coloring.<\/p>","protected":false},"featured_media":4294,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[18],"product_tag":[19],"class_list":{"0":"post-4232","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-petroleum-additives","7":"product_tag-petroleum-additives","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product\/4232","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/comments?post=4232"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/media\/4294"}],"wp:attachment":[{"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/media?parent=4232"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_brand?post=4232"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_cat?post=4232"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/chemneo.com\/pt\/wp-json\/wp\/v2\/product_tag?post=4232"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
